     詳細

    中赤外アップコンバージョン方は感度,応答速度,解像度などの点ですぐれた可視イメージングセンサを用いて,中赤外イメージを得る方法として有望である.しかし,変換後の可視光が微弱であるという課題がある.この課題を解決するために,本研究では中赤外アップコンバージョンゴーストイメージングを提案し,その実現可能性について検討することを目的とする.

     詳細

    再生可能エネルギー源による発電量の増加により,リアルタイムで電流を計測する重要性が増している.光ファイバ電流センサは感電や漏電の危険性がなく,遠隔からの計測が可能という利点を有する.光ファイバによる電流の検出は,電流に付随する磁場が光ファイバ中の直線偏光を回転させることを利用するため,ヴェルデ定数の大きな材料が光ファイバ電流センサに適する.変形や温度変化に起因する応力によって偏光の乱れが生じることから,光弾性係数がゼロである材料を使用する必要がある.これらの条件を満たし,熱的安定性が高い材料として,鉛シリケートガラスが用いられてきた.しかし,近年,各国の規制により鉛の使用は制限されるようになり,光ファイバ電流センサ用の無鉛ガラスの開発が強く望まれている.本研究では,鉛シリケートガラスの代替可能なテルライトガラスを見出すことを目的とする.

    2022年度
    In 2017, Stone et al. presented a silica multicore fiber with low index contrast image thanks to a special structure where same sized cores would never be neighbors, decreasing significantly the crosstalk between cores. More recently, Tuan et al. successfully created a long (10cm) all-solid tellurite glass disordered fiber (TDOF) with good image transportation at different wavelength (1.4 to 1.6µm). It is, though, known that the problem of disordered fiber is that image transmission can be distorted due to oversized clusters of fibers of same refractive indices. By coupling these two research, this work tries to find how to obtain better results compared to the TDOF previously reported in view of coupling efficiency or image resolution by using a honeycomb-like network with different sized neighbor cores with controlled randomness.

  • 複屈折率テルライト光ファイバ中の四光波混合、誘導ラマン散乱および相互位相変調によるスーパーコンティニューム光の発生

    大石 泰丈, 鈴木 健伸

    2018年度 - 現在

     詳細

    The supercontinuum (SC) generations in a birefringent TeO2-ZnO-Na2O-Bi2O3 (TZNB) tellurite microstructured optical fiber (BTMOF) have been demonstrated by pumping near the zero-dispersion wavelengths (ZDWs) with a tunable picosecond erbium-doped fiber laser.

    成果:

    2022年度
    When the pump is polarized parallel with the x-axis of the BTMOF, the SC broadening is governed by the four-wave mixing (FWM), stimulated Raman scattering (SRS) and cross-phase modulation (XPM). The FWM signal can be generated from 1538 to 1293 nm, and the idler can be emitted from 1597 to 1907 nm. Due to the high nonlinear property of the BTMOF, the XPM between the FWM signal and idler can be significantly amplified by the cascaded FWM effect. When the pump is polarized parallel with the y-axis of the BTMOF, the SC is broadened by the Stokes and anti-Stokes SRS. A broadest Stokes SRS band with a 10-dB bandwidth of 232 nm is generated by pumping at 1545 nm with an average pump power of 23.8 dBm. Potentially, widely tunable fiber lasers can be developed by exploring the FWM or SRS in highly nonlinear tellurite fibers with tailored dispersion profiles. The SC evolutions agree well with the numerical simulation.

    We report here the design of a new chalcogenide hybrid microstructured optical fiber (HMOF) with a buffer layer around the core and its potential performance of tailoring chromatic dispersion and supercontinuum (SC) generation.

    成果:

    2022年度
    The new chalcogenide HMOF has an AsSe2 core. The refractive index difference ∆n between the AsSe2 core and cladding material is supposed to be 0.3. The fiber microstructure and the ∆n between the core and buffer materials are designed in order to obtain broad anomalous dispersion regimes with near-zero and flattened chromatic dispersion profiles for broadband SC generation. Moreover, the suppression of chromatic dispersion fluctuation caused by fiber transverse geometry variation is investigated. By using the proposed chalcogenide buffer-embed HMOFs, the calculation shows that near-zero and flattened anomalous chromatic dispersion regimes from 4.5 µm can be obtained. When the variation of fiber structure occurs for ±1, ±5 and ±10 %, the chromatic dispersion fluctuation can be greatly suppressed. In addition, the calculation shows that a broad SC spectrum from 2.5 to more than 16.0 μm can be obtained when a 0.9-cm-long section of the new chalcogenide buffer-embed HMOF is pumped at 5.0 μm by a femtosecond laser with 1-kW peak power.

    2022年度
    In the late 1980s, it was proposed that an optical wave system in which the refractive index profile is random in the transverse plane but is invariant in the longitudinal direction supported the transverse localization of light. The transport of optical images using transverse localization of light and its potential applications in biological and medical imaging were demonstrated by using a polymer optical fiber. The experimental results showed that after a CW probe beam propagated in our 5-cm-long fabricated tellurite optical rod, the beam became localized. With the potential of tellurite glasses such as high nonlinearity, broad transmission window and the control of the refractive index difference, the performance of image transport through a tellurite disordered optical medium by transverse localization of light is expected to improve in the near future.

  • スーパーコンティニュームのコヒーレンスに及ぼす3次の波長分散の効果

    鈴木 健伸, 大石 泰丈

    2018年度 - 現在

     詳細

    The effect of third-order dispersion on the coherence properties of supercontinuum spectra has been numerically investigated by solving the generalized nonlinear Schrödinger equation and using the complex degree of coherence theory.

    成果:

    2022年度
    First, the effect of third-order dispersion on the coherence properties of supercontinuum spectra generated by soliton fission and soliton self-frequency shift has been investigated. The results show that if the group velocity dispersion values at the pump wavelength are identical and under the identical pumping conditions, negative third-order dispersion can cause much larger intensity fluctuations and wavelength jitters at the red edge of generated solitons than positive third-order dispersion, resulting in higher coherence degradation. Then the effect of negative third-order dispersion on the coherence properties of supercontinuum spectra generated by soliton fission and soliton self-frequency shift compensation has also been investigated. When at low input laser peak powers, due to the combined effects of modulation instability, negative third-order dispersion and the second zero-dispersion wavelength, the coherence depending on the input laser peak power decreases steeply first and then increases. When at high input laser peak powers, the modulation instability, negative third-order dispersion and soliton collision significantly contribute to the coherence degradation. The second zero-dispersion wavelength cannot stabilize the red-shifted solitons.

    2022年度
    Supercontinuum (SC) generation in optical fibers has been a topic of great interest because it can provide multiwavelength optical sources with high coherence and brightness which are useful for many potential applications such as wavelength division multiplexing transmission, optical frequency combs, spectroscopy and optical coherence tomography. However, SC spectra can also suffer from significant fluctuations in amplitude and it is important that the SC source is generated with low noise and with high spectral flatness. Recently, tellurite glasses have been employed for MOFs instead of silica glasses due to their high nonlinearity, wide transmission in the mid-IR region, low attenuation and high thermal stability. Several efforts have been devoted to obtain tellurite MOFs with flattened dispersion profiles because they can enhance the nonlinear spectral broadening and the spectral flatness of SC generation. But, they require very complex fiber structures which are difficult to be fabricated.
    In order to control chromatic dispersion profile of tellurite fibers in higher extent but simplify their fiber structure, our group proposed a tellurite hybrid microstructured optical fiber (HMOF). The fiber was successfully fabricated and its chromatic dispersion was tailored to be near-zero and flattened with three zero-dispersion wavelengths at 1270, 1973 and 3627 nm.

  • 広帯域光パラメトリック増幅用高非線形光ファイバの波長分散ゆらぎの抑制

     詳細

    In this work, we study the suppression of chromatic dispersion fluctuation and the performance of FOPA in a tellurite hybrid microstructured optical fiber (HMOF) with buffer layer by taking into account the variation in the core diameter and fiber transverse geometry.

    成果:

    2022年度
    Fiber-based optical parametric amplification (FOPA) is one of typical applications of four-wave-mixing (FWM) in highly nonlinear optical fibers which can transfer energy from one or two strong pump fields to a weak signal field and generate a new idler field. Since FOPA can provide broad gain bandwidths and high signal gain in many spectral bands where other types of optical amplifier cannot reach, it has been exploited for various applications such as signal amplification, wavelength conversion, phase-conjugation, slow and fast lights, optical signal processing and biomedical applications. However, high efficiency of FOPA performance is not easy to be obtained. It requires suitable pump sources, optical fibers with high nonlinearity and appropriate designs of chromatic dispersion which can satisfy the phase-matching condition. One of important technical issues for FOPA performance is that phase-matching condition for FWM in optical fibers is very sensitive to the fluctuation of chromatic dispersion which is caused by the fiber transverse geometry variation. A new fiber structure has been reported to suppress the chromatic dispersion fluctuation for silica fiber on the supposition that only the core diameter varies along the fiber length.
    It was shown that tellurite HMOF with buffer layer is more advantageous to suppress the chromatic dispersion fluctuation and to improve the FOPA signal gain and bandwidth than conventional tellurite HMOF without buffer layer. By optimizing the diameters and refractive indices of the core and buffer layer so as to effectively suppress the chromatic dispersion fluctuation, HMOF with buffer layer can be a promising medium to overcome the influence of fiber transverse geometry variation on the performance of FOPA.

    Here, a tellurite step-index fiber with large core is fabricated to keep the zero-dispersion wavelength (ZDW) of the fundamental mode close to that of the material dispersion which is located in the near-infrared region.

    成果:

    2022年度
    Four-wave mixing (FWM) in optical fibers is promising for wavelength conversion in optical networks due to its ultrafast response and high bit rate transmission. To further improve the performance of FWM-based wavelength conversion such as its bandwidth and conversion efficiency, the low nonlinearity of silica fibers should be improved by using novel highly nonlinear soft-glass fibers such as lead-silicate, bismuth-oxide, tellurite and chalcogenide fibers. By using a femtosecond pulsed laser pumped in the vicinity of the ZDW, it is expected to broaden and extend the bandwidth of the FWM-based wavelength conversion towards the near-infrared window for potential applications. When the pump wavelength was tuned from 1647 to 1795 nm, the signal was tuned from 1550 to 1434 nm, and the idler was generated from 1757 to 2400 nm. A 17.5 dB maximum signal gain at 1550 nm and +1.1 dB idler conversion efficiency at 1757 nm were obtained. When the pump wavelength was 1795 nm, the signal and generated idler wavelengths were 1434 and 2400 nm, respectively. To the best of our knowledge, this is the first time to demonstrate a FWM-based wavelength conversion performance whose wavelength spacing is ~966 nm (from 1434 to 2400 nm) in a tellurite step index optical fiber as short as 1 m.

    Multiple Raman peak properties in a 130 m tellurite fiber is investigated using different pump sources.

    成果:

    2022年度
    When a nanosecond laser operated at ~1545 nm was used as the pump source, second-order Raman shift with multiple Raman peaks was observed. Especially for the first-order Raman shift, six obvious Raman peaks were obtained. To the best of our knowledge, this was the first demonstration of multiple Raman peaks in tellurite fibers. When a picosecond laser operated at ~1064 nm was used as the pump source, second-order Raman shift with only dual Raman peaks was observed, which can be applied to tunable lasers and amplifiers. Furthermore, the influence of fiber length on the evolution of Raman shift was investigated using a 2.5 m tellurite fiber. The reduction in fiber length led to a lower Raman gain, which induced only dual Raman peaks in each order Raman shift.

    For the first time, an all-solid tellurite optical glass rod with a transversely disordered refractive index profile was fabricated successfully as a medium to study the transverse localization of light and near-infrared (NIR) optical image transport. Two tellurite glass compositions of 70TeO2-8Li2O-17WO3-3MoO3-2Nb2O5 (TLWMN) and 75TeO2-15ZnO-5Na2O-5La2O3 (TZNL) which have a small difference in softening temperature (about 0.5 °C), compatible thermal expansions from room to 400 °C and broad transmission range from about 0.4 up to 6.0 µm were developed for a successful fabrication process. The tellurite transversely disordered optical rod (TDOR) consists of high and low-index units (TLWMN and TZNL, respectively). The diameter of each unit is 1.0 μm and their refractive index difference was about 0.095 at 1.55 µm. Experimental results showed that after a CW probe beam at 1.55 μm propagated in a 10-cm-long tellurite TDOR, the beam became localized. In addition, NIR optical images at 1.55 μm of numbers on a test target were transported. The captured images at the output facet of the tellurite TDOR are visually clear with high contrast and high brightness. The quality of our transported optical images can be comparable or higher than the results which were obtained by a polymer Anderson localized fiber and by a commercially available multicore imaging optical fiber.

    Nd3+-doped P2O5-Al2O 3-K2O-BaO (LHG-8) glasses were prepared and the internal quantum efficiency (QE) of near-infrared emission of the glasses were directly measured with a simulated sunlight source and an 800 nm laser. The stimulated emission cross section (σ) and the radiative emission lifetime (τr) were also obtained by Judd-Ofelt analysis. The QE of Nd 3+:LHG-8 under the simulated sunlight was as high as 60% at the Nd2O3 concentration of 0.05 mol%, and this value was higher than those of Nd3+-doped oxide glasses, such as borosilicate, silicate, and tellurite glasses. The στr of LHG-8 was also higher than those of the other Nd3+-doped oxide glasses. © 2012 Elsevier B.V. All rights reserved.

    The internal quantum efficiencies under sunlight and laser excitation were measured directly by an integrating sphere method for tellurite, borosilicate and fluoride glasses. The radiative quantum efficiency was also obtained by Judd-Ofelt analysis. The radiative quantum efficiency was almost 100% for tellurite and fluoride glasses and 50% for borosilicate glasses. The quantum efficiency under laser excitation was 86%, 34% and 88% for tellurite, borosilicate and fluoride glasses at a low Nd3+ content and decreased by concentration quenching. The quantum efficiency under sunlight excitation was up to 33%, 21% and 70% for tellurite, borosilicate and fluoride glasses. Nd3+-doped fluoride glass is a promising candidate for solar pumped laser applications since it has the high quantum efficiency under sunlight excitation. (C) 2011 Elsevier B.V. All rights reserved.

    The absorption and fluorescence characteristics of Er doped and Nd, Er codoped fluoride glasses were investigated under illumination of the simulated sunlight, laser or a monochromatic light filtered from a Xe lamp. Er was used as a sensitizing agent enhancing the energy conversion and the emission efficiency of Nd ions in fluoride glass intended for the sunlight excitation. Er doped fluoride glasses showed four emission peaks under simulated sunlight illumination at the wavelengths of 550, 848, 980, and 1530 nm attributed to the electronic transitions of Er3+ ions. The quantum efficiency of the emission from all of the bands had a peak at x = 0.5 mol. % Er and with the maximum of 73 %. The intensity of each emission band showed different ratios for various ErF3 contents. It is expected that concentration quenching of S-4(3/2) state is easy to occur with high concentration of ErF3 compared to the other states. The energy transfer from Er to Nd was studied using a monochromatic light illumination which is absorbed by Er3+ ions only. Strong contribution of Er absorption to the 1.05 mu m emission of Nd, Er co-doped fluoride glass was observed. Er was confirmed as a suitable sensitizer for the enhanced energy conversion and emission efficiency of Nd ions in ZBLAN glasses which are proposed for highly efficient solar pumped fiber lasers.

    Transparent glass-ceramics containing YLiF4 nano-crystals were synthesized by controlled heat treatment of LiF-YF3-Al2O3-SiO2 glass. The crystallite size, estimated to be about 8 nm, was much less than the wavelength of visible light. From the fluorescent properties of the Er3+-doped precursor glass and the glass-ceramic, it was confirmed that Er3+ could be incorporated into YLiF4 nano-crystallites in the glass-ceramic. This transparent glass-ceramic containing YLiF4 nano-crystals is promising as a gain medium for rare earth-doped fiber lasers and amplifiers. (C) 2010 The Japan Society of Applied Physics

    A systematic method to evaluate potentials of Ni2+-doped transparent glass-ceramics as a new broadband optical gain media is presented. At first, near-infrared emission of various ceramics were investigated to explore the suitable crystalline phase to be grown in the glass-ceramics. The quantum efficiency of Ni2+ near-infrared emission estimated by the Struck-Fonger analysis was higher than 95% for spinel-type structure gallate crystals MgGa2O4 and LiGa5O8 at room temperature. Transparent glass-ceramics containing Ni2+ : LiGa5O8 could be prepared and the quantum efficiency for the glass-ceramics was measured to be about 10%. This value shows a potential of Ni-doped transparent glass-ceramics as a broadband gain media. (c) 2007 Elsevier B.V. All rights reserved.

    Crystal growth and spectroscopic characterization of Ni-doped MgGa(2)O(4) belonging to inverse-spinel structure crystal family are described. Single crystals of this material were grown by floating zone method for the first time. Oxygen gas flow was essential to minimize evaporation of Ga(2)O(3) during the floating zone crystal growth process. Bubble and inclusion-free crystals were obtained for the growth rate less than 5 mm/hour. Ni:MgGa(2)O(4) single crystal was characterized by broadband fluorescence in 1100-1600 nm wavelength range and 1.6 msec room-temperature lifetime. It could be attributed to the transition of (3)T(2)((3)F)->(3)A((2)F) transition of the octahedrally coordinated Ni(2+). The internal quantum efficiency of the near-infrared fluorescence was about 82 % for 1 mol% Ni-doped MgGa(2)O(4) single crystal at room temperature. The new material is to be very promising for tunable laser applications covering the important optical communication, eye safe, 1100-1600 nm wavelength.

    A broad near-infrared emission of Bi-doped lithium alumino silicate glasses has been investigated. It was found that the peak wavelength and width of the emission from the glasses could be controlled drastically by the excitation wavelength. The emission spectrum had the broadest bandwidth of more than 500 nm under 900 nm excitation. The emission consisted of two Gaussian peaks and the stimulated emission cross sections at the peaks were calculated as 7.3x10(-21) and 2.3x10(-20) cm(2). The lifetime was almost independent of temperature up to 350 K, indicating that the emission from the Bi-doped lithium alumino silicate glass has strong resistance to the thermal quenching.

    Glass-ceramics were obtained from Li2O-Ga2O 3-SiO2-NiO system glass. Opaque glass-ceramics were obtained by heat treatment of the temperatures above 973 K. Crystalline phases in the opaque glass-ceramics were identified as LiGaSi2O6 and LiGa5O8. Transparent glass-ceramics were obtained by heat treatment of the temperature range from 923 K to 953 K. The transparent glass-ceramics included a spinel type LiGa5O8 nanocrystals. The average diameter was about 5 nm. Suppression of generation of LiGaSi2O6 phase is a key point of heat treatment condition to obtain transparent glass-ceramics. Crystal field analyses of absorption spectra of Ni2+ ions revealed that Ni2+ ions in the glass-ceramics occupy octahedral sites and the crystal field parameters of Ni2+ in the glass-ceramics agreed well with that in LiGa 5O8. This fact suggests that the most of Ni2+ ions in the transparent glass-ceramics were included in LiGa5O 8 nanocrystals. The transparent glass-ceramics exhibited broadband near-infrared emission covering the wavelength region from 1100 nm to 1600 nm, which has never been observed in as-quenched glasses. The emission could be attributed to the transition from 3T2g to 3A2g state of octahedral Ni2+. The emission lifetime was more than 900 μsec at 5 K and 500 μsec even at 300 K. The emission quantum efficiency was measured by using an integration sphere. It was about 9.1 %, which is enough high as a practical gain medium.

    Transparent glass-ceramics were prepared from Ni2+-doped ZnO Al2O3-SiO2 (ZAS) system glasses by annealing. The color of the glasses drastically changed from brownish yellow to green by annealing. The crystalline phase being precipitated by annealing was identified as solid solutions of spinel compounds. The crystalline sizes estimated by transmission electron microscope observation in Ni2+-doped post-annealed glasses were about 10-15 nm in diameter, while that in non-doped post-annealed glasses were 510 nm. This suggests that Ni2+ ions in ZAS glass were incorporated into the crystalline phases as nucleation agents of crystallization. It was confirmed from optical absorption measurements that Ni2+ ions occupied fivefold sites in the as-cast glass, while Ni2+ ions occupied octahedral sites in the post-annealed glass. The Ni2+-doped post-annealed glasses exhibited near-infrared emission. It is thought that the crystals containing Ni2+ ions act as emission centers. (c) 2005 Elsevier B.V. Ail rights reserved.

    Broadband near-infrared emission from Ni2+ in zinc-alumino-silicate glass was observed at room temperature. The emission band had a peak at similar to1400 nm with a bandwidth more than 300 nm, and covered the O, E, S, C, and L bands (1260-1625 nm). The emission lifetime was more than 200 mus even at room temperature. The observed near-infrared emission could be attributed to the (3)A(2g)(F-3)--&gt;T-3(1g)(F-3) transition of Ni2+ in octahedral sites. This nickel-doped glass can be expected as an amplification medium for tunable lasers and broadband optical amplifiers for the wavelength division multiplexing transmission system applications.

    This paper describes a prospect for broadband mid-infrared (mid-IR) highly coherent supercontinuum generation. Tellurite and chalcogenide glass with high transparency up to the mid-IR range are used as fiber materials. We successfully develop all-solid hybrid microstructured optical fibers made of tellurite and chalcogenide glass to control chromatic dispersion and demonstrate that highly nonlinear soft glass microstructured optical fibers are promising media for broadband mid-IR highly coherent supercontinuum generation.

    A specific probe-type sensor based on an optical fiber metasurface was proposed and simulated for refractive index (RI) sensing. In this work, a metasurface has been integrated with an optical fiber platform, which has huge potential applications in imaging, sensing, and communications. The designed RI sensor consists of stacking layers of Au and ZnO in a 2D structure deposited on the end face of commercial multimode optical fiber. The parameters and performance of the sensor structure are designed and simulated. The results show that the designed sensor structure can generate mode resonance and realize RI sensing. Numerical simulations reveal that when the pair of Au/ZnO layers is 4, the width of the nanopillars is 300 nm, the thickness of the Au layer is 45 nm, the thickness of ZnO layer is 40 nm, and the RI sensitivity of the designed sensor reaches 1415 nm/RIU. In addition, the high RI of Au/ZnO, along with its compatibility with the fiber core (SiO2), makes it a perfect candidate to realize a multifunctional device. It also is a the biocompatible material that can be functionalized easily and used to realize biosensing.

    An antiinterference temperature sensor based on the Mach-Zehnder interferometer (MZI) is proposed, which is formed by successively fusing a homemade Kagome hollow-core photonic crystal fiber (HC-PCF) with two no-core fibers (NCFs) and two single-mode fibers (SMFs). Because of the antiresonant reflection optical waveguide properties, the interference between hollow-core mode and glass mode is achieved in Kagome HC-PCF, which significantly simplifies the overall sensing architecture and maintains better stability of the sensing signal. Using a Kagome HC-PCF length of $497 \mu \text{m}$ , the maximum temperature sensitivity of the proposed sensor is obtained as 38.39 pm/°C. Meanwhile, it exhibits a low sensitivity of 0.5041 pm/ $\mu \varepsilon $ to ambient stress variation, -0.28 nm/ $\text{m}^{-{1 } }$ to curvature change, and 9.35 nm/RIU to external refractive index (RI) change. This MZI temperature sensor has the advantages of compact structure, easy fabrication, low cost, small size, high sensitivity, and antiinterference capability, which can be expected to be applied to temperature sensing in complex environments.

The doping of Mo6+ ions allowed enhanced luminescence at moderate power pumping, avoiding the introduction of undesired laser-induced thermal effects while improving the spectral signal-to-noise ratio. The luminescence characteristics were investigated in detail at different doping molar ratio of Mo6+ ions, and the strongest was observed at 8 mol%. Drawing on tri-doped TZLB glass with the strongest UC emission intensity, a tri-doped TZLB fiber was fabricated and coupled with two multimode fibers (MMFs) via Ultraviolet (UV) adhesive, forming the temperature sensor. The sensor was further encapsulated by a silica tube sealed with Ultraviolet adhesive, overcoming the poor mechanical property of tellurite fiber. The temperature information could be demodulated based on the fluorescence intensity ratio technique. The temperature sensing performance of the tri-doped TZLB sensor was investigated as temperature varied from 258 to 420 K and its repeatability was experimentally verified. The Er3+/Yb3+/Mo6+ tri-doped TZLB has an application prospect in the field of lighting, and the so-based temperature sensor is expected to be applied to thermal detection in the fields of medical diagnostics, environmental monitoring, and optical thermometers, etc.

    We demonstrate a plug-in tip sensor with a maximum cross section diameter of only 1 mm for real-time thermal monitoring of a high-density miniature winding coil, which can meet the miniaturization development needs of electromagnetic actuators. Due to the high upconversion luminescence efficiency, tellurite glass with an optimized Er3+/Yb3+ doping ratio is adhered to the end face of silica fiber for a temperature-sensitive tip. Temperature information is demodulated using the fluorescence intensity ratio technique, yielding a nonlinear response with R2 up to 0.9978. Within a wide temperature range of 253.55–442.45 K, the tip sensor exhibits good repeatability, excellent stability, high sensitivity of 52.7 × 10−4 K−1, small absolute error within ±1 K, and fast time response of 2.03 s. It has been successfully proven to be a miniaturized device with strong anti-interference ability for the health management of high-density winding coils.

    In this paper, we report a successful fabrication of a highly nonlinear chalcogenide all-solid hybrid microstructured optical fiber with polarization maintaining properties and a mid-infrared SC generation. Up to 4.5 × 10−4 at 10 µm of the fiber birefringence can be realized by employing a single As2Se3 core and two As2S5 rods horizontally aligned in the AsSe2 cladding. The fiber possesses a near-zero and flattened all-normal chromatic dispersion profile over the wavelength range from 5 to 10 µm. The polarization maintaining properties of the fiber is experimentally confirmed and a broadband supercontinuum spectrum from 2 to 10 µm in the mid-infrared window was experimentally demonstrated.

    In this paper, a no-core tellurite optical fiber (NCTOF)-based sensor was proposed for cryogenic temperature detection in refrigeration process. The ultraviolet adhesive (UVA) dual-curing method was operated to stablish a sandwich-like composite structure, in which a section of NCTOF was compactly sandwiched between two segments of silica fiber to form multimode interference. The temperature sensing characteristics in cryogenic range were experimentally investigated by monitoring the transmission spectral movement, where a high sensitivity of 105.6 pm/°C was achieved in the range of −20-0 °C and 51.6 pm/°C in the range of −20-25 °C. The excellent performance was consistent with the simulation analysis. The maximum repeatability standard deviation and stability wavelength error of the sensor are 0.9799 pm/°C and 0.1676 nm, respectively. To the best of our knowledge, this is the first report on using tellurite optical fibers for cryogenic temperature detection, and the UVA dual-curing method provides a reliable solution for the integration and practical application of tellurite optical fiber. The proposed sensor is simple in structure, easy in fabrication, low in cost and excellent in performance. It can be expected to be used in food refrigeration, air-conditioning engineering, medical and health, industrial production, etc.

    In this paper, a temperature-control optical switch is designed based on a conjoined-tubular anti-resonance optical fiber (CTF). The CTF adopts eight pairs of conjoined tubes and four vertical-layout holes were coated with Au to increase the fiber confinement loss (Loss). Toluene was used as transmission medium to injected into the CTF core. The proposed switch produces a Loss difference over 100 dB and ER more than 30 dB. Influence of switch material refractive index and structural parameters on optical switch performance was further discussed. The proposed optical fiber switch has the features of simple structure, small size, broad working wavebands and adjustable operation temperature, which promises broad application prospects in industry, chemistry, biology and other fields.

    A novel fiber-optic soliton self-frequency shift (SSFS) temperature sensor fabricated using an in-house-made microstructured optical fiber was proposed. Based on this sensor, SSFS-based sensing was systematically investigated with the variation of average pump power and pump wavelength. By detecting the central wavelength shift of the 3-dB bandwidth of the soliton with the change in temperature, the sensing performance of the proposed sensor was evaluated experimentally and theoretically, subject to the average pump power and pump wavelength. At the generation of the fundamental soliton, when the pump wavelength was fixed, the higher the average pump power, the higher the temperature sensitivity. When the average pump power was fixed, the longer the pump wavelength, the higher the temperature sensitivity. The maximum temperature sensitivity of the proposed sensor was 1.759 nm/℃ at an average pump power of 300 mW and pump wavelength of 1600 nm. This temperature sensor exhibited excellent properties, such as high sensitivity, a simple structure, an easy fabrication process, good mechanical strength, and low cost, rendering it highly applicable in fields such as food quality control, environmental monitoring, and biomedical testing.

    We theoretically proposed the concept of temperature sensing using the soliton self-frequency shift (SSFS) effect in a fluorotellurite microstructured fiber (FTMF) which had one ring of six alcohol-infiltrated air holes. The glass material for the fiber core was 70TeO2–20BaF2–10Y2O3 and the cladding AlF3–BaF2–CaF2–YF3–SrF2–MgF2–TeO2. Based on SSFS effect, temperature sensing in the mid-infrared (MIR) region was achieved by detecting the wavelength shift of solitons with the variation of temperature. Using a 2800 nm fiber laser with a pulse width of 131 fs as the pump light and a 0.5-m-long FTMF as the nonlinear media, the temperature sensing sensitivity could be as high as 2.09 nm/°C. To the best of our knowledge, this is the first study concerning temperature sensing in the MIR region by drawing on SSFS effect in a non-silica FTMF.

    In this work, the temperature (strain) properties of As2Se3 pi-phase-shift fiber Bragg gratings (pi-PSFBGs) are numerically investigated. The sensing sensitivities are 0.0665 nm degrees C-1 (0.8598 pm mu epsilon(-1)) at 1.55 mu m, 0.1546 nm degrees C-1 (1.9968 pm mu epsilon(-1)) at 3.6 mu m, 0.2717 nm degrees C-1 (3.51 pm mu epsilon(-1)) at 6.328 mu m, and 0.4551 nm degrees C-1 (5.8796 pm mu epsilon(-1)) at 10.6 mu m, and the sensitivities are improved with the increasing Bragg wavelength. Based on them, a high-performance narrow band fiber laser is theoretically proposed. The proposed tunable laser has a wider wavelength adjustment range in mid-infrared region, which can reach 27.306 nm at around 10.6 mu m. Moreover, the obvious Bragg wavelength shift induced by stretching the As2Se3 pi-PSFBG helps widen the tunable range of the laser, making possible a fine tuning. Being simple in structure and high in sensitivity, the proposed laser can be applied in mid-infrared region, which is the fingerprint region of numerous molecules and which closely relates to military aviation, environmental conservation, biology and health care regions.

    We report on mid-infrared gas spectroscopy measurements by means of the supercontinuum (SC) absorption spectroscopy method. We developed a 80 MHz-repetition-rate mid-infrared SC light source with an average power of 40 mW generated through nonlinear propagation of 200 fs pulses in a 10 cm-long segment of step-index tellurite fiber. A compact multipass cell is used for analyzing absorption of CO2 and CH4 gases and their mixture in the 2-3.5 µm spectral range. Experimental results are compared to the HITRAN database.

    Passively mode-locked pulses generated in a thulium-doped fiber laser was demonstrated by the ReS2 nanoparticles. The ReS2 nanoparticles are introduced into the laser cavity on a side polished fiber through optical deposition method, which works as a saturable absorber. Self-starting mode-locking can be established quickly when the pump power is higher than 700 mW. The central wavelength and the 3 dB bandwidth of single pulse operation are 1970.65 and 5.05 nm, respectively. The pulse repetition is 26.1 MHz and the full width at half maximum is 893 fs with the time-bandwidth product of 0.348.

    Brillouin gain spectra (BGS) in an As2Se3 photonic crystal fiber (PCF) are investigated numerically. The profiles of the BGS are simulated by calculating the characteristics of different-order optical and acoustic waves in the PCFs with different core diameters. For the small-core PCF, there are two peaks in BGS, but there is only one peak for the large-core PCF. We also reveal that in the small-core PCF, the difference of Brillouin frequency shift between the LP01 and LP11 modes is obvious, while it is not obvious in the large-core PCF. The Brillouin threshold increases with the core diameter increasing.

    In this work, we demonstrate a wide-spectrum multi-wavelength fiber laser generated by Brillouin-comb assisted four-wave mixing (FWM). The mechanism of the laser is based on the combination of stimulated Brillouin scattering in cavity and multiple FWM process outside cavity. The experiment results demonstrate that Brillouin-comb assisting is an effective method to improve the FWM process and increase the line number. More than 110 lines are achieved in 10 nm spectral range with the wavelength spacing of ∼0.09 nm. The multi-wavelength fiber laser exhibits good stability on both the operating wavelengths and output power. The tunability of this multi-wavelength fiber laser is improved significantly by inserting a tunable filter in the cavity. The total line number is kept more than 110 in the whole tunable range of 30 nm from 1540 to 1570 nm.

    We report a design, analysis, and numerical modeling of a tapered chalcogenide step-index fiber for broadband high-power mid-infrared supercontinuum extending from the 1.5-14.5 μm molecular 'fingerprint region'. The reported tapered chalcogenide fiber structure is able to generate a broadband supercontinuum spectrum with output average power of 82mW (27.7mW for the wavelengths >5 μm) when it is pumped with 200 fs laser pulses with a repetition rate of 76MHz and average power of 200mW at 3.5 μm. Such a bright and broadband mid-infrared supercontinuum light source covering both the 3-5 μm and 8-13 μm atmospheric windows and most of the molecular fingerprint spectral region has practical applications in various fields, including mid-infrared spectroscopy, imaging, and biomedical diagnostics.

    A linear mode-locked fiber laser based on the semiconductor saturable absorption mirror was demonstrated to realize mode locking in group velocity locked vector soliton regime and polarization rotation vector soliton regime. The highly fixed birefringence was introduced into the linear fiber laser cavity by using a piece of polarization maintaining Erdoped fiber. The vector nature of pulse of the mode-locked fiber laser was experimentally studied. It turned out that, this birefringence enhanced mode-locked fiber laser can generate both group velocity locked vector soliton and polarization rotation vector soliton though slightly changing the birefringence of the laser cavity. The experimental results reveal the fundamental physics of group-velocity locked vector soliton and polarization rotation vector soliton generation and demonstrate that the linear birefringence enhanced fiber laser is a good platform for investigating the vector soliton.

    A W-type co-axial chalcogenide optical fiber structure is designed and numerically analysed for the broadband and highly coherent supercontinuum sources in the mid-IR region. The structural parameters of the designed W-type optical fiber are optimized to obtain small absolute group velocity dispersion in broad spectral range in the mid-IR region. The proposed W-type fiber structure possesses a flat dispersion profile with the flatness of the dispersion of ±2.45 ps/nm/km in the spectral range of 4.9 - 12.6 μm. The broadband and coherent mid-IR supercontinuum spectrum extending from 2.28 μm to 15.52 μm at -40 dB level is obtained using a 4 cm long chalcogenide W-type fiber pumped by 200 fs laser pulse of peak power of 10 kW at 7 μm. The average coherence property of the supercontinuum spectrum is almost unity in the full spectral range for the chalcogenide W-type fiber. Such broad and highly coherent mid-IR supercontinuum spectrum is very important because most of the biological tissue possesses their molecular fingerprints within this spectral range. Therefore, this region of electromagnetic spectrum is extremely useful to determine a tissue spectral map which provides very important information concerning the existence of the critical diseases such as cancer. The W-type chalcogenide fiber structure reported in this paper is a promising candidate for the development of the coherent broadband mid-IR supercontinuum sources which have potential applications in early cancer diagnostic, food quality control, gas sensing, and imaging.

    We experimentally demonstrate tunable Brillouin comb generation in a ring cavity composed of a piece of tellurite single mode fiber. The tunable Brillouin comb lines are separated with frequency space of 7.9 GHz, which is equal to the Brillouin frequency shift in the tellurite fiber. Due to the high Brillouin gain coefficient of the tellurite fiber, a tellurite fiber as short as 200 m was inserted into the ring cavity. Cascaded stimulated Brillouin Stokes and anti-Stokes lines are generated in the ring cavity leading to multi-wavelength Brillouin comb generation bi-directionally. By tuning the narrow-linewidth tunable laser, we can tune the Brillouin comb in the wide range of 1533 nm to 1565 nm.

    Mid-infrared cascaded stimulated Raman scattering (SRS) is experimentally investigated in an As-S optical fiber which is fabricated based on As38S62 and As36S64 glasses and whose fiber loss is ∼0.08 dB/m at1545 nm. Using a nanosecond laser operated at ∼1545 nm as the pump source, mid-infrared cascaded SRS up to eight orders is obtained in a 16 m As-S fiber. To the best of our knowledge, this is the first demonstration of SRS of such high order in non-silica optical fibers, and it may contribute to developing tunable mid-infrared Raman fiber lasers using C-band pump sources.

    A rib waveguide structure in As2Se3 chalcogenide glass has been designed and numerically analyzed for on-chip coherent supercontinuum generation in the midinfrared region. The waveguide structure possesses an all-normal dispersion profile with dispersion value of −13.22 ps∕nm · km at the pump wavelength. Coherent midinfrared supercontinuum spectrum spanning 1.2 to 7.2 μm has been obtained using a 2.5 mm long rib waveguide when pumped with 200 fs laser pulses of a peak power of 2.5 kW and a repetition rate of 1 kHz at 2.8 μm. Such highly nonlinear subwavelength size rib waveguide structures are highly applicable for the power efficient on-chip midinfrared coherent supercontinuum sources. Coherent midinfrared supercontinuum sources are very important in frequency metrology, nonlinear microscopy, nondestructive testing, molecular spectroscopy, and optical coherence tomography.

    We have examined the effects of Bi concentration, annealing in air, and addition of reducing agent on the near-infrared (NIR) emission of Bi-doped TiO2-ZnO-B2O3-Al2O3 (TZBA) glass. Since the decay constants of the NIR emission are independent of the Bi concentration and the preparation conditions, it is expected that a small part of Bi species can act as effective activators in the glass. Annealing affects the blue shift and broadening of the NIR emission. The change in the bandwidth upon Bi or AlN addition can be explained from the viewpoint of the viscosity of the glass melt, which seems to be one of the important factors for obtaining broadband-emitting materials.

    A tellurite all-solid photonic bandgap fiber (ASPBF) whose cladding consists of 60 high-index rods arranged periodically around a central core was successfully fabricated. The diameter of high-index rod was about 5.0 μm and the distance between the center of two adjacent high-index rods was approximately 8.0 μm. The high-index rod was made of the TeO2-Li2O-WO3-MoO3-Nb2O5 (TLWMN) glass, the cladding was made of the TeO2-ZnO-Na2O-La2O3 (TZNL) glass as the background glass material and the central core was made of TZNL glass doped with 0.5 wt% of Nd2O3. A supercontinuum light from 0.6 to 2.4 μm was coupled into the core of fiber which is 2.2 cm long to measure its transmission spectrum. High transmission bands were obtained in the vicinity of 0.75 and 1.3 μm but the transmission was suppressed in the wavelength range from 1.0 to 1.06 μm. When a titanium Sapphire laser source at 0.75 μm was used, the emission spectrum was obtained with two peaks at 1.06 and 1.33 μm which are attributed to the 4F3/2→4I11/2 and 4F3/2→4I13/2 transitions of Nd3+ ion, respectively. The intensities of those emission peaks were compared with those obtained from a bulk glass having the same doping concentration of Nd3+. The results showed that by using tellurite ASPBF, the intensity of the 1.06-μm emission was suppressed by one-twelfth but the intensity of the 1.33-μm emission was maintained. This feature is very advantageous to filter out the 1.06-μm emission of Nd3+ ion in order to realize practical amplifier devices at 1.3 μm.

    The supercontinuum generation and rogue wave generation in a step-index chalcogenide fiber are numerically investigated by solving the generalized nonlinear Schrodinger equation. Two noise models have been used to model the noise of the pump laser pulses to investigate the consistency of the noise modeling in rogue wave generation. First noise model is 0.1% amplitude noise which has been used in the report of rogue wave generation. Second noise model is the widely used one-photon-per-mode-noise and phase diffusion-noise. The results show that these two commonly used noise models have a good consistency in the simulations of rogue wave generation. The results also show that if the pump laser pulses carry more noise, the chance of a rogue wave with a high peak power becomes higher. This is harmful to the SC generation by using picosecond lasers in the chalcogenide fibers.

    We successfully synthesized Er3+-Yb3+ doped cubic phase NaYF4 nanocrystals by a facile solvethermal method. The average size of the as-prepared nanocrystals was about 12 nm based on the observation of scanning electron microscope and transmission electron microscope. NaYF4/SiO2 nanoparticles were prepared. The thickness of shell layer was about 7 nm. The as-prepared samples were annealed at different temperature. The cubic phase NaYF4 did not transit to hexagonal phase, but to amorphous phase as the annealing temperature increased to 700 degrees C. When temperature further increased to 1100 degrees C, the amorphous NaYF4 reacted with SiO2 shell and formed a new phase, NaYSiO4. Under the excitation by a 976 nm laser, the Er3+-Yb3+ doped NaYF4, NaYF4/SiO2, and NaYSiO4 nanoparticles showed intense visible upconversion emissions. Since the host materials changed from fluoride crystals to amorphous fluoride, then to silicate crystals, the spectral profiles were different. Fluorescent lifetimes obtained from decay curves were applied to analyze the multi-phonon relaxation processes in different hosts. The Er3+-doped upconversion phosphors will be useful for light converting in solar cell applications in the future.

    We demonstrate the effects of stimulated Raman scattering (SRS) in the all-solid-core chalcogenide microstructured optical fibers (MOFs) with AsSe2 core and As2S5 cladding, which are fabricated by the rod-in-tube drawing technique. The core diameters of the MOFs are similar to 6.3 (Fiber I), 3.0 (Fiber II), 2.6 (Fiber III) and 2.2 (Fiber IV) mu m, respectively. The chromatic dispersion of the fundamental mode in Fibers I-IV is simulated by the full-vectorial mode solver technique. The first-order Stokes wave is investigated in the fibers with different core diameters pumped by the picosecond pulses at 1958 nm. In Fiber I, no obvious Raman peak is observed with the pump power increasing, because the effective nonlinearity is not high. In Fiber II, a Raman Stokes peak at similar to 2065 nm begins to emerge at the pump power of 110 mW. The conversion efficiency is as weak as -36.6 dB at 150 mW pumping. In Fiber III, the first-order Raman peak at similar to 2060 nm begins to emerge at 40 mW pumping. The conversion efficiency is -15.0 dB, which is 21.6 dB higher than that in Fiber II. In Fiber IV, the Stokes peak at 2070 nm begins to appear at 56 mW pumping. The maximum conversion efficiency of the first-order Stokes wave is obtained in the MOF with the core diameter of 2.6 mu m. The evolution of the first-order Stokes wave with pump power and fiber length is investigated. This is the first demonstration of Raman effects in the AsSe2-As2S5 MOF, to the best of our knowledge.

    The present paper proposed an interactive segmentation method of pancreases in abdominal computed tomography (CT) images based on the anatomical knowledge of medical doctors and the statistical information of pancreas shapes. This segmentation method consisted of two phases: training and testing. In the training phase, pancreas regions were manually extracted from sample CT images for training, and then a probabilistic atlas (PA) was constructed from the extracted regions. In the testing phase, a medical doctor selected seed voxels for a pancreas and background in a CT image for testing by use of our graphical user interface system. The homography transformation was used to fit the PA to the seeds. The graph cut technique whose data term was weighted by the transformed PA was applied to the test image. The seed selection, the atlas transformation, and the graph cut were executed iteratively. This doctor-in-the-loop segmentation method was applied to actual abdominal CT images of fifteen cases. The experimental results demonstrated that the proposed method was more accurate and effective than the conventional graph cut.

    The optical and acoustic fields of stimulated Brillouin scattering (SBS) and the interaction between them are investigated in the As2S3 chalcogenide suspended-core microstructured optical fibers (MOFs) by the finite-element method (FEM). The optical and acoustic fundamental modes are analyzed at 1550 nm. The core diameters of the MOFs vary from 1.0 to 6.0 mu m. For each case, the holes of the MOFs are filled with different materials such as trichlormethane (CHCL3), alcohol and water. When the core diameter is 6.0, 4.5, 3.0, 2.0 and 1.0 mu m, the ratios of difference for optical fields are similar to 0.66%, 0.97%, 1.48%, 1.94% and 3.55%, respectively, while the ratios of difference for acoustic fields are similar to 0.13%, 0.24%, 0.34%, 0.74% and 29.13%, respectively. The overlap factors between optical and acoustic fields are calculated, which change with the core diameter and the filled material. The results will be helpful to strengthen or suppress the SBS effect in practical applications. (C) 2017 Elsevier GmbH. All rights reserved.

  • Mid-infrared supercontinuum generation in chalcogenide multi-step index fibers with normal chromatic dispersion 査読

    We experimentally demonstrate mid-infrared supercontinuum (SC) generation in chalcogenide multi-step index fibers (MSIF) pumped by a femtosecond laser. The fabricated chalcogenide MSIF is composed of a high refractive index core (C1) in the center, which is enclosed by a lower refractive index core layer (C2) and an outer cladding. This fiber structure is advantageous to tailor the chromatic dispersion with higher freedom and to keep the effective mode area small at long wavelengths. The high refractive index core, low refractive index core, and the outer cladding materials are As2Se3, AsSe2 and As2S5, respectively. When the diameter of C1 and C2 are 7.8 and 30 mu m, respectively, the zero-dispersion wavelength (ZDW) of the fiber is 12.5 mu m. The chromatic dispersion profile is near-zero and flattened within the range of +/- 20 ps/km/nm in the wavelength range from 4 to 17 mu m and a broad normal dispersion region is obtained in the wavelength range shorter than the ZDW. In practice, a 2.8 cm long fiber is pumped at 10 mu m by using a femtosecond laser whose pulse width is similar to 200 fs. The SC generation extending from 2 to 14 mu m is obtained. Most of its spectrum is in the normal dispersion region of the fiber. These results are promising for the highly coherent mid-infrared SC generation.

    We demonstrate the supercontinuum (SC) generation in a chalcogenide step-index fiber with AsSe2 core and As2S5 cladding. The characteristics of fiber are analyzed using the full-vectorial mode solver technique. The fiber has two zero-dispersion wavelengths at 2898 and 5140 nm. The evolving of SC spectra with fiber length and pump wavelength is investigated experimentally. The maximum SC range covering one octave from 1550 to 3300 nm is obtained when the 20 cm long fiber is pumped by 2000 nm pulses in normal dispersion region. The fiber can push forward the nonlinear application based on the stimulated Raman effect, stimulated Brillouin effect, four-wave mixing, supercontinuum generation, and so on in the mid-infrared waveband. The SCs are simulated by the nonlinear Schrodinger equation. The simulated results agree well with the experiments. (C) 2016 The Japan Society of Applied Physics

    Energy transfer between Tm3+ and Tb3(+) dependent on the power density of pump laser was investigated in NaYF4: Tb3+, Tm3+, Yb3+ microcrystals. Under the excitation of a 976-nm near-infrared laser at various power densities, Tb3+-Tm3+-Yb3+ doped samples exhibited intense visible emissions with tunable color between green and blue. The ratio of blue and green emission were determined by energy transfer between Tm3+ and Tb3+. When the power density of pump laser was low, the energy transfer process from Tm3+ (F-3(4)) to Tb3+ (F-7(0)) occurred efficiently. Upconversion processes in Tm3+ were inhibited, only visible emissions from Tb3+ with green color were observed. When the power density increased, energy transfer from the F-3(4) (Tm3+) to F-7(0) level (Tb3+) was restrained and population on high energy levels of Tm3+ was increased. Contribution of upconversion emissions from Tm3+ gradually became dominant. The emission color was tuned from green to blue with increasing the power density. Energy transfer processes between low-lying levels of activators, such as Tm3+ will greatly reduce the population on certain levels for further high-order upconversion processes. The Tb3+-Tm3+-Yb3+ doped phosphors are promising materials for detecting the condition of power density of the invisible near-infrared laser. (C) 2016 Optical Society of America

    Wavelength-tunable picosecond degenerate four-wave mixing was demonstrated in a tellurite microstructured optical fiber (TMOF). The zero-dispersion wavelength of the TMOF was shifted to 1570nm by introducing a single ring of air holes in the cladding. The anti-Stokes signal sideband can be generated from 1490 to 1500 nm, and the Stokes idler sideband can emit from 1595 to 1645 nm. Because of the high nonlinearity of the TMOF and the large peak power of the picosecond pump, a maximal signal gain of 31.2 dB and an idler conversion efficiency of +35 dB were achieved.

    A broadband fibre-optical parametric amplifier (FOPA) operating at a novel wavelength region that is far from the pump wavelength has been demonstrated by exploiting two pairs of adjacent four-wave mixing (FWM) sidebands generated simultaneously in a tellurite microstructured optical fibre (TMOF). Owing to the large nonlinearity of the TMOF and the high pump peak power provided by a picosecond laser, a maximal average gain of 65.1 dB has been obtained. When the FOPA is operated in a saturated state, a flat-gain amplification from 1424 nm to 1459 nm can be achieved. This broadband and high-gain FOPA operating at new wavelength regions far from the pump offers the prospect of all-optical signal processing.

    We experimentally demonstrate mid-infrared (MIR) super-continuum (SC) generation spanning similar to 2.0 to 15.1 mu m in a 3 cm-long chalcogenide step-index fiber. The pump source is generated by the difference frequency generation with a pulse width of similar to 170 fs, a repetition rate of similar to 1000 Hz, and a wavelength range tunable from 2.4 to 11 mu m. To the best of our knowledge, this is the broadest MIR SC generation observed so far in optical fibers. It facilitates fiber-based applications in sensing, medical, and biological imaging areas.

    The effects of stimulated Raman scattering (SRS) is demonstrated in chalcogenide microstructured optical fiber (MOF) with allsolid AsSe2 core and As2S5 cladding. The first-order Raman Stokes wave is investigated in the MOFs with different core diameters pumped by the picosecond pulses at 1958 nm. The maximum conversion efficiency of -15.0 dB from the pump to first-order Raman Stokes wave is obtained in the MOF with the core diameter of 2.6 mu m. The conversion efficiency decreases when the core diameter deviates from 2.6 mu m. When the fiber core is larger, the effective nonlinearity is decreased. When the fiber core is smaller, the mode field is difficult to be confined in the core. The walk-off length between the pump and Stokes wave is crucial to the process of SRS according to the analysis of the experimental data. The Raman effects are simulated numerically. The simulated results can agree well with the experiments. It is the first time to demonstrate the Raman effect in AsSe2-As2S5 MOF, to the best of our knowledge. (C) 2016 Optical Society of America

    Abstract

    We design and fabricate an all-solid chalcogenide microstructured optical fiber (MOF) with four rods in the cladding, in order to generate mid-infrared (MIR) dispersive waves (DWs). The high-index background is made of AsSe2 glass, and the four low-index rods are made of As2S5 glass. This MOF has two zero-dispersive wavelengths: ∼3,720 and 4,230 nm. The propagation loss is ∼1.9 dB/m at 2,000 nm, and the nonlinear coefficient is ∼4 × 103 km−1 W−1 at 3,000 nm. Using a pulse of ∼80 MHz and ∼200 fs emitted from an optical parametric oscillator as the pump source, the resulting MIR DWs are investigated at different pump wavelengths.

    A high numerical aperture (NA) step-index fiber with As2Se3 core and As2S5 cladding was fabricated for deep mid-infrared (MIR) transmission over 10 mu m. MIR supercontinuum generation covering the wavelength from 3 to 10 mu m was successfully demonstrated in this fiber using a MIR pulsed laser source with mu J-level energy output around 7 mu m. A 4-cm-long fiber sample is sufficient to enable a spectral broadening spreading from 3 to 10 mu m in a 20 dB dynamic range. (C) 2016 The Ceramic Society of Japan. All rights reserved.

    We successfully synthesized Er3+/Yb3+ co-doped KY3F10 nanocrystals by a facile hydrothermal method. The average size of the as-prepared nanocrystals was about 60 nm based on the observation of scanning electron microscope. Under the excitation of a 976 nm laser, the Er3+/Yb3+ doped KY3F10 nanocrystals showed intense near-infrared emission band centered at 1539 nm. The optimal concentrations of Er3+ were carefully selected according to the quantum yield measurement for a stronger emission in the C-band. The as-prepared nanocrystals were dispersed into a monomer, bisphenol A ethoxylate diacrylates, in which self-written waveguides can be fabricated under the irradiation of an induced laser at 450 nm. The KY3F10: Er3+/Yb3+ nanocrystals embedded polymer waveguide were fabricated by laser-induced self-written technique. Two pieces of single mode fiber were well connected with the waveguide in the fabrication procedure. Under a 976 nm laser pumping, amplified spontaneous emission at 1539 nm was observed in the KY3F10:Er3+/Yb3+ nanocrystals doped waveguide.

    The performance of fiber-optical parametric amplification is studied by employing the AsSe2-based hybrid microstructured optical fiber (HMOF). By adding a buffer layer around the core with appropriate diameter and refractive index difference, the chromatic dispersion profile of chalcogenide HMOFs can be tailored to have a near-zero and flattened anomalous dispersion regime in the mid-infrared window. A very broad gain bandwidth can be achieved from 3.0 to 9.0 mu m by pumping at 4.7 mu m. The signal gain can be as high as 32 dB. In addition, the HMOF with buffer layer can suppress the chromatic dispersion variation caused by the fiber structure fluctuation and maintain the signal gain spectrum.

    We experimentally demonstrate multiple dispersive waves (DWs) emitted by multiple mid-infrared solitons in a birefringence tellurite microstuctured optical fiber (BTMOF). To the best of our knowledge, this is the first demonstration of multiple DWs in the non-silica fibers. By using a pulse of similar to 80 MHz and similar to 200 fs emitted from an optical parametric oscillator (OPO) as the pump source, DWs and solitons are investigated on the fast and slow axes of the BTMOF at the pump wavelength of similar to 1800 nm. With the average pump power increasing from similar to 200 to 450 mW, the center wavelength of the 1st DW decreases from similar to 956 to 890 nm, the 2nd DW from similar to 1039 to 997 nm, the 3rd DW from similar to 1101 to 1080 nm, and the 4th DW from similar to 1160 to 1150 nm. Meanwhile, obvious multiple soliton self-frequency shifts (SSFSs) are observed in the mid-infrared region. Furthermore, DWs and solitons at the pump wavelength of similar to 1400 and 2000 nm are investigated at the average pump power of similar to 350 mW. (C) 2015 Optical Society of America

    We demonstrate the broadband cascaded four-wave mixing (FWM) and supercontinuum (SC) generation in a tellurite MOF which is made from 76.5TeO(2)-6ZnO-11.5Li(2)O-6Bi(2)O(3) (TZLB, mol%) glass. By using a 2-mu m picosecond laser with the center wavelength of similar to 1958 nm as the pump source, the broadband FWM with the frequency separation of similar to 1.1 THz is obtained. The bandwidth of the frequency comb spans a range of similar to 630 nm from similar to 1620 to 2250 nm at the average pump power of similar to 125 mW. With the average pump power increasing to similar to 800 mW, the broadband mid-infrared SC generation with the spectrum from similar to 900 to 3900 nm is observed. Changing the pump source to a femtosecond laser (optical parametric oscillator, OPO) with the center wavelength of similar to 2000 nm, solitons and dispersive waves (DWs) are obtained.

    Nonlinear optical polymers show promising potential applications in photonics, for example, electro-optical devices. Poly (methyl methacrylate) (PMMA) is widely used in optical waveguides, integrated optics and optical fibers. However, PMMA has not been used for nonlinear optical waveguides since it has a low nonlinear refractive index. We successfully prepared chalcogenide amorphous nanoparticles doped PMMA that had a high nonlinearity. The As3S7 bulk glass was dissolved in propylamine to form a cluster solution. Then the As3S7/propylamine solution was added into methyl methacrylate (MMA) containing photoinitiator Irgacure 184 about 0.5 wt%. After well mixing the As3S7 nanoparticle doped MMA was transparent. Under the irradiation by a 365 nm UV lamp, As3S7 nanoparticles doped PMMA was obtained with yellow color. The third-order nonlinear optical susceptibility of As3S7 nanoparticles doped PMMA was investigated. An optical waveguide array based on the As3S7 nanoparticles doped PMMA composite of high nonlinearity was fabricated.

    We report here flattened supercontinuum (SC) generated in tellurite-phosphate and chalcogenide-tellurite hybrid microstructured optical fibers (HMOFs) whose chromatic dispersion spectra are tailored with high freedom due to large refractive index difference (Delta n) between the core and cladding glasses. It is shown in the simulation that the tellurite-phosphate HMOF whose chromatic dispersion spectrum is near-zero and flattened with three zero-dispersion wavelengths (ZDWs) over a wide wavelength range from 1000 to 4000 nm is beneficial to obtain broad and flattened SC spectra. By using a large Delta n of 0.49, the tellurite-phosphate HMOF which has flattened chromatic dispersion and three ZDWs is successfully fabricated. When a 20-cm-long tellurite-phosphate HMOF is pumped at 1550 nm with a 1560-W peak power, an SC extended from similar to 800 to 2400 nm where similar to 5-dB spectral flatness in the wavelength ranges from 890 to 1425 nm and from 1875 to 2400 nm (similar to 1060-nm bandwidth in total) is observed. In addition, a flattened SC spectrum with similar to 6-dB spectral flatness over a broad wavelength range from 950 to 3350 nm (2400-nm bandwidth in total) is generated by pumping a 1-cm-long chalcogenide-tellurite HMOF at 2300 nm with a 40-MW peak power.

    An elliptical core tellurite microstructured optical fiber with high birefringence was demonstrated and the chromatic dispersion of the two orthogonal modes in this fiber was experimentally characterized by a white light spectral interferometric technique over a wide spectral range. A series of spectral interferograms as a function of the optical path difference were recorded in the Mach-Zehnder interferometer. The birefringence dependence of the wavelength in the fiber was determined by interferograms. The measured and calculated dispersion matched well within the whole spectrum range under test.

    A novel AsSe2-As2S5 hybrid MOF (HMOF) is designed and fabricated by the rod-in-tube drawing technique. The core is made from AsSe2 glass and the cladding is made from As2S5 glass. The loss is similar to 1.2 dB/m at similar to 3000 nm. Zero dispersion wavelength (ZDW) of the HMOF is similar to 3380 nm. Supercontinuum (SC) generation in a 2 cm-long HMOF is investigated with the pump wavelengths of similar to 3062, 3241 and 3389 nm from a tunable optical parametric oscillator (OPO) system. Broadband mid-infrared (MIR) SC generation with the spectrum from similar to 1256 to 5400 nm is obtained with the peak power of similar to 1337 kW at the wavelength of similar to 3389 nm.

    We demonstrate third-harmonic generation (THG) with a tunable spectral range of more than 500 nm in a step-index tellurite fiber. Third-harmonic (TH) signals with a peak wavelength from 524 to 1043 nm are obtained in a 3 cm-long fiber when the fundamental wavelength shifts from 1560 to 3100 nm. To our knowledge, the tunable spectral range covering almost one octave is the widest tunable range of THG in fibers so far. The far-field patterns of the TH signals by 1560 nm to 2100 nm pumping are recorded by a charge coupled device camera, which are close to the fundamental mode profile. The THG in such a wide tunable range is attributable to the high nonlinearity of the tellurite fiber and the high pump peak power of the pump pulse.

    We demonstrate the supercontinuum (SC) generation in a four-hole As2S5 chalcogenide microstructured optical fiber (MOF) experimentally. The As2S5 glass has better property of transmission than As2S3 glass in the visible range. The four-hole As2S5 MOF is fabricated by a rod-in-tube method. The SCs generated by different pump wavelengths at 2,000, 2,300 and 2,500 nm in the MOF whose length is from 2.3 to 20 cm are demonstrated. Those pump wavelengths correspond to the chromatic dispersion wavelength in the normal chromatic dispersion region, the anomalous chromatic dispersion region close to zero-dispersion wavelength (ZDW) and the anomalous chromatic dispersion region far from ZDW, respectively. Wider SCs can be obtained when pumped at a wavelength in the anomalous dispersion region close to ZDW. The widest SC range of 4,280 nm (from 1,370 to 5,650 nm) covering two octaves was obtained in a 4.8-cm-long fiber pumped at 2,300 nm.

    We report fabrication of a highly nonlinear hybrid microstructured optical fiber composed of chalcogenide glass core and tellurite glass cladding. The flattened chromatic dispersion can be achieved in such an optical fiber with near zero dispersion wavelength at telecommunication wavelengths lambda = 1.35-1.7 mu m, which cannot be achieved in chalcogenide glass optical fibers due to their high refractive index, i.e. n &gt; 2.1. We demonstrate a hybrid 4-air hole chalcogenide-tellurite optical fiber (Delta n = 0.25) with flattened chromatic dispersion around lambda = 1.55 mu m. In optimized 12-air hole optical fiber composed of the same glasses, the chromatic dispersion values were achieved between -20 and 32 ps/nm/km in a broad wavelength range of 1.5-3.8 mu m providing the fiber with extremely high nonlinear coefficient 86,000 km(-1) W-1. Hybrid chalcogenide/tellurite fibers pumped with the near infrared lasers give good promise for broadband optical amplification, wavelength conversion, and supercontinuum generation in the near- to mid-infrared region.

    Oleate-capped alpha-NaYF4:1% Nd3+ nanocrystals (NCs) of various sizes were successfully synthesized by a solvothermal method. Citrate-capped and Polyethylenimine (PEI)-capped alpha-NaYF4:1%Nd3+ NCs were prepared via ligand exchange reactions of oleate-capped samples. Under the excitation at 808 nm, all samples showed intense near-infrared (NIR) emissions. Quantum efficiencies (QEs) and emission lifetimes of samples of various sizes and different adsorbed ligands were measured. The quenching effects of the adsorbed ligands were investigated using a quenching model. It was observed that the ligands with long methylene groups strengthened the quenching effect that led to low QEs and short emission lifetimes. (C) 2014 The Japan Society of Applied Physics

    The linear phase-mismatch and the optical signal gain in the highly nonlinear tellurite hybrid microstructured optical fiber based on the degenerate four-wave mixing are numerically simulated. The core and the cladding of this fiber are designed by TeO2-Li2O-WO3-MoO3-Nb2O5 and TeO2-ZnO-Na2CO3-P2O5 glass, respectively. This fiber has high nonlinearity and at the same time the chromatic dispersion is flattened and close to zero. High optical signal gain and broad band can be obtained by using a short length of this fiber with low pump power. (C) 2014 Elsevier B.V. All rights reserved.

    A hybrid four-hole AsSe2-As2S5 microstructured optical fiber (MOF) is fabricated by the rod-in-tube drawing technique. The core is made of AsSe2 glass and the cladding is made of As2S5 glass. The material refractive indices of the core and the cladding are similar to 2.832 and similar to 2.219 at the wavelength of similar to 2.8 mu m, respectively. The calculated zero-dispersion wavelength of the AsSe2-As2S5 MOF is 2.759 mu m. Soliton self-frequency shift with a soliton central wavelength from 2.986 to 3.419 mu m is observed when the AsSe2-As2S5 MOF is pumped by an optical parametric oscillator at the pump wavelength of similar to 2.8 mu m. At the same time a blue-shift dispersive wave is emitted by the soliton. (C) 2014 AIP Publishing LLC.

    Soliton self-frequency shift (SSFS) and third-harmonic generation (THG) are observed in a four-hole As2S5 chalcogenide microstructured optical fiber (MOF). The As2S5 MOF is tapered to offer an ideal environment for SSFS. After tapering, the zero-dispersion wavelength (ZDW) shifts from 2.02 to 1.61 mu m, and the rate of SSFS can be enhanced by increasing the energy density of the pulse. By varying the average input power from 220 to 340 mW, SSFS of a soliton central wavelength from 2.206 to 2.600 mu m in the mid-infrared is observed in the tapered segment, and THG at 632 nm is observed in the untapered segment.

    Alternative materials to silica glass are necessary for supercontinuum (SC) generation at longer wavelengths in the mid-infrared (MIR) region. The alternative materials should possess the properties of wide transmission window and high nonlinearity, simultaneously. Chalcogenide glass is the suitable candidate due to its excellent properties of transmission and nonlinearity in MIR region. In this paper, we demonstrate the SC generation in a suspended-core As2S3 chalcogenide microstructured optical fiber (MOF). The variation of SC is investigated by changing the fiber length, pump peak power and pump wavelength. In the case of long fibers (20 and 40 cm), the SC ranges are discontinuous and stop at the wavelengths shorter than 3500 nm, due to fiber absorption. In the case of short fiber as 2.4 cm, the SC range is continuous and can extend to the wavelengths longer than 4 m. The process of SC broadening is observed when the pump peak power increases from 0.24 to 1.32 kW at 2500 nm in the 2.4 cm long fiber. The variation of SC range with the pump wavelength changing from 2200 to 2600 nm is studied. The selected wavelengths correspond to the dispersion of As2S3 MOF from the normal to anomalous region. The SC generation is simulated by the generalized nonlinear Schrodinger equation. The simulation includes the SC difference between 1.3 and 2.4 cm long fiber at 2500 nm pumping and the variation of SC with pump peak power in 2.4 cm long fiber. The simulation agrees well with the experiment.

    A four-hole AsSe2-As2S5 hybrid microstructured optical fiber (HMOF) with a large refractive index difference is fabricated by the rod-in-tube drawing technique. The core and the cladding are made from the AsSe2 glass and As2S5 glass, respectively. The propagation loss is ∼1.2 dB/m and the nonlinear coefficient is ∼4.937×104 km-1W-1at ∼3000 nm. Zero dispersion wavelength (ZDW) of the HMOF is ∼3380 nm. Supercontinuum (SC) generation in the HMOF is investigated by pumping a 2 cm-long AsSe2-As2S5 HMOF with the wavelengths of ∼3062, 3241 and 3389 nm from a tunable optical parametric oscillator (OPO) system. Broadband mid-infrared SC generation with the spectrum from ∼1256 to 6385 nm is obtained with the peak power of ∼1337 kW at the wavelength of ∼3389 nm.

    Chalcogenide microstructured fibers (MOFs) have great advantages for supercontinuum (SC) generation in mid-infrared (MIR) region, because they possess the properties of high nonlinearity and wide transmission window, simultaneously. The nonlinear parameters of chalcogenide MOFs can be higher by several tens or hundreds than those of silica, fluoride and tellurite fibers depending on the material components and fiber structures. Chalcogenide MOF can be transparent from visible up to the infrared region of 12 or 15 mu m depending on the compositions. In this paper, we demonstrate the SC generation in two kinds of suspended-core chalcogenide MOFs with different material components and fiber structures. One is an As2S3 MOF with three-hole structure (Fiber I). The other is an As2S5 MOF with four-hole structure (Fiber II). For Fiber I, the SC range of 3020 nm (from 1510 to 4530 nm) were obtained in a 2.4 cm fiber, when pumped by the wavelength at 2500 nm. The SC extends to the wavelengths longer than 4 mu m. For Fiber II, the SC range of 4280 nm (from 1370 to 5650 nm) is generated in a 4.8 cm fiber when pumped by the wavelength at 2300 nm, which covers more than two octaves. Compared to the SC generated in Fiber I, the SC spectral range in Fiber II has been increased by more than 1200 nm due to the better transmission property of the As2S5 glass; the SC extends to the wavelengths longer than 5 mu m.

    The parametric amplification gain and bandwidth in highly nonlinear tellurite hybrid microstructured optical fiber (HMOF) are simulated based on four wave mixing process. The fiber core and cladding materials are made of TeO2-Li2O-WO3-MoO3-Nb2O5 and TeO2-ZnO-Na2O-P2O5 glass, respectively. The fiber has four zero-dispersion wavelengths and the chromatic dispersion is flattened near the zero-dispersion wavelengths. A broad gain bandwidth as wide as 1200 nm from 1290 to 2490 nm can be realized in the near infrared window by using a tellurite HMOF as short as 25 cm.

    Er3+/Yb3+ co-doped LiYF4 nanocrystals were prepared by a facile solvothermal method. By adjusting the LiOH concentration, LiYF4 crystals with the size range from 16 nm to 2.0 mu m were synthesized. Under the excitation by a 976 nm laser, upconversion quantum efficiency of the LiYF4: Er3+/Yb3+ samples were measured. It was observed that upconversion quantum efficiency tended to decrease with the reduction of particle size from microscale to nanoscale. A model was proposed to clarify the surface quenching mechanism influencing the size-dependent upconversion luminescence. (C) 2013 Optical Society of America

    We demonstrate the supercontinuum (SC) generation in a suspended-core As2S3 chalcogenide microstructured optical fiber (MOF). The variation of SC is investigated by changing the fiber length, pump peak power and pump wavelength. In the case of long fibers (20 and 40 cm), the SC ranges are discontinuous and stop at the wavelengths shorter than 3500 nm, due to the absorption of fiber. In the case of short fibers (1.3 and 2.4 cm), the SC ranges are continuous and can extend to the wavelengths longer than 4 mu m. The SC broadening is observed when the pump peak power increases from 0.24 to 1.32 kW at 2500 nm. The SC range increases with the pump wavelength changing from 2200 to 2600 nm, corresponding to the dispersion of As2S3 MOF from the normal to anomalous region. The SC generation is simulated by the generalized nonlinear Schrodinger equation. The simulation includes the SC difference between 1.3 and 2.4 cm long fiber by 2500 nm pumping, the variation of SC with pump peak power in 2.4 cm long fiber, and the variation of SC with pump wavelength in 1.3 cm long fiber. The simulation agrees well with the experiment. (C) 2013 Optical Society of America

    An ultra-broadband supercontinuum (SC) covering 0.2-8.0 mu m which is more than 5 octaves, is demonstrated in a piece of fluoride glass. The 20 dB bandwidth spans from 0.39 to 7.4 mu m. The filaments, bright conic visible emission, and interference fringe pattern are observed. The glass thickness, optical path, and pump conditions are optimized to enable the SC to cover the entire transmission range of the glass, which includes the whole functional group region of chemical bands and groups. The SC conversion efficiency is confirmed to be stable. (C) 2013 The Japan Society of Applied Physics

    Although soft glass such as tellurite or chalcogenide glass is transparent in the range of 3-6 mu m, fiber made of it is difficult to generate as a supercontinuum (SC) to that range because of the high loss, the wavelength limit of the pump source, and the challenges in light-coupling. To circumvent these problems, we developed an SC light source by using tellurite bulk glass through filamentation. For this scheme, the optical path length in the glass is very short due to the adopted high pump power, so the negative influence of material loss is reduced greatly. The light-coupling is straightforward, and the coupling efficiency is high. The bulk glass for SC generation is cheap, and can be fabricated easily. We have shown that under suitable pump conditions, the SC generation by filamentation can cover from visible to 6 mu m. It is the broadest SC generation by tellurite (including glass and fiber). For suitable pump conditions, the glass was free of optical breakdown. If the interface reflections were deducted, the SC conversion efficiency was 87%; the SC conversion efficiency was stable. To the best of our knowledge, this is the first report on filamentation in tellurite glass which has a comparatively small bandgap.

    Chalcogenide glass has great advantages because of their wide transmission window and high nonlinearity in the mid-infrared (MIR) region. Many works about supercontinuum (SC) generation in As-Se or As-S fibers have been demonstrated [1-2]. In this paper, we demonstrate the SC generation in a 1.3 cm suspended-core As2S3 microstructured optical fiber (MOF) experimentally. The SC range changed with different pump wavelengths from 2200 to 2600 nm, corresponding to the dispersion from the normal to anomalous region. The SCs could extend to longer than 4 μm with the pump wavelengths close to the zero-dispersion wavelength (ZDW). The SCs were simulated by the generalized nonlinear Schrödinger equation. © 2013 IEEE.

    The oleate-capped α-NaYF4:Nd3+ nanocrystals (NCs) were synthesized via solvothermal method. By a ligand exchange method, the oleate-capped NCs could be changed to citrate-capped samples which can be dispersed in polar solvents. By the relation between the measured emission lifetime and effective refractive indices of the composites containing NCs, the local field effect was investigated. It was found that the preferable model would change from the real cavity model to virtual cavity model when the particle size reduced to 6 nm in nonpolar solvent system, but the preferable model kept being real cavity model in polar solvent system. © 2013 IEEE.

    We optimized the optical pump power to realize better phase-matching, higher parametric amplification gain and broader bandwidth for highly nonlinear optical fibers with tailored chromatic dispersions. The core-clad materials have large refractive index difference of 0.49. The gain bandwidth calculated are 108 and 104 nm for the step index and hybrid micorstructured optical fibers with two zero dispersion wavelengths respectively. The broadest bandwidth in our calculation is 108 nm for step index fiber at pump wavelength 1238 nm.

  • Supercontinuum generation from a multi-ring holes tellurite microstructured fiber pumped by a 2 micron high power mode-locked fiber laser 査読

    Supercontinuum (SC) generation from a highly nonlinear tellurite microstructured fiber with multi-ring holes was demonstrated by pumping with a 2 mu m high power mode-locked fiber laser. The chromatic dispersion of the fiber was measured with a homemade white-light spectral interferometer on a wide wavelength range and matched very well with the theoretical calculation. The zero dispersion wavelength (ZDW) of the fiber was measured to be 1358 nm and calculated to be 1390 nm. Although the pumped wavelength was far away from ZDW, with flat dispersion profile of the fiber on the anomalous dispersion, the SC could be expanded from 650 nm to 2850 nm with launched pulse energy of several hundred picojoules. Simulations of SC generation were performed and showed fair agreement with the experimental results.

    Pure alpha-NaYF4:Nd3+ nanocrystals of various sizes from 6 to 18 nm were successfully synthesized by a solvothermal method. By controlling the doping concentration of Nd3+ ions, alpha-NaYF4 nanocrystals with different quantum efficiencies were prepared. The monodispersed oleate-capped nanocrystals were dispersed in several nonpolar solvents to obtain stable colloids. Under the excitation by an 803 nm laser, luminescent decay curves of the colloids were measured. The relationship between the emission lifetimes of samples and the effective refractive indices of solvents was studied. The local field correction factor for the samples of 18 nm with different quantum efficiencies is expressed by the real cavity model which indicates the local field effect is independent of the emission quantum efficiency. When the particle size decreases to 6 nm, the preferred model alters from the real cavity model to the virtual cavity model which might be derived from changing of polarizability density.

    The quantum efficiency (QE) of Er3+-doped silicate, tellurite, phosphate and fluoride glasses have been examined under simulated sunlight excitation. The maximum of total QE, the sum of QE of S-4(3/2), I-4(11/2), I-4(13/2)-&gt; I-4(15/2) and S-4(3/2)-&gt; I-4(13/2) transition, is 75% and the maximum of QE1530, the QE of the I-4(13/2)-&gt; I-4(15/2) transition at 1530 nm, is 34 % for 5.47x10(19) cm(-3) Er3+-doped fluoride glass. The figure of merit as laser media st of silicate glass is 1.00x10(-22) cm(2)sec, which is the highest in 4 glasses. Although QE1530 of silicate is lower than fluoride, it is possible to compensate the low quantum efficiency to optimize the fiber laser design. Therefore Er3+-doped fluoride and silicate glasses are expected to be promising candidates as solar-pumped glass laser. (C) 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim

    Pure alpha-NaYF4: Nd3+ nanocrystals of various sizes from 6 nm to 18 nm were successfully synthesized by a solvothermal method. The monodispersed oleate-capped nanocrystals were dispersed in several nonpolar solvents to obtain stable colloidal. Under the excitation by an 803 nm laser, luminescent decay curves of the colloidal were measured. The relationship between emission lifetimes of samples and effective refractive indices of solvents was studied for the local field correction factor. In the 18 nm sample, the real cavity model was preferable model. As the particle size decreased to 6 nm, the preferred model altered from the real cavity model to the virtual cavity model which might be derived from changing of polarizability density.

    Four wave mixing and supercontinuum from tellurite photonic crystal fibers have been widely researched. Their efficiencies depend largely on fiber nonlinearity and chromatic dispersion. Since we have shown that the composite microstructured optical fibers (CMOFs) can have high flexibility on chromatic dispersion control when refractive index difference between core and cladding becomes larger, cladding materials with much lower refractive index than tellurite glass are required. We report here a novel tellurite core-phosphate cladding CMOF. Phosphate glasses which thermal expansion coefficient, viscosity, glass transition, deformation and crystallization temperatures are close to those of tellurite 78TeO(2) - 5ZnO - 12Li(2)O - 5Bi(2)O(3) mol% (TZLB) glass are systematically investigated. The phosphate glasses we developed have high transparency and broad transmission region up to 3 mu m as well as notably low refractive indices. Using the phosphate glasses doped with mixed-alkali oxides obtained in this work, the refractive index difference between core and cladding becomes as high as 0.5 which is sufficiently high to control the chromatic dispersion with high freedom. Our work shows that tellurite-phosphate CMOFs are promising candidates as highly nonlinear fibers with freely controlled chromatic dispersion for nonlinear applications.

    We demonstrate visible light generation in chalcogenide As2S3 microstructured optical fiber. The generated visible light causes irreversible damage to the fiber core because of the high absorption coefficient of chalcogenide glasses in the visible band. The SCs (supercontinua) are measured in both untapered and tapered As2S3 fibers, no wider SC is obtained in the tapered one. The SC growth is prevented by the visible light generation since the damage to the fiber core decreases the fiber transmission substantially. This effect can be avoided by designing the fiber to enable the pump source to work in single-mode operation. (C) 2011 The Japan Society of Applied Physics

    We demonstrate a general technique for realizing fine control of optical pulse width via doublet gain or loss lines. The optimized doublet gain or loss lines for fine control of optical pulse width can be designed by using an inverse design method. The preliminary experimental demonstration of fine control of optical pulse width is performed by using doublet Brillouin gain lines in an optical fiber. Tunable pulse compression or stretching ratio of 1.47-0.43 accompanying a time delay is achieved by controlling the separation between two gain lines, for an input pulse train with a 40 ns pulse width and a repetition rate of 5 MHz, in a 4 km silica fiber with a fixed pump power of 88.1 mW.

    In this paper we report emission from Bi doped gallium lanthanum sulphide (Bi:GLS) glass with a full width at half maximum (FWHM) of 600 nm which is flattened and covers the entire telecommunications window. The excitation wavelength of this emission was 1020 nm, the quantum efficiency (QE) was 17%, the lifetime was 160 mu s and product of the emission cross section and lifetime (sigma(em)tau) was 2x10(-25) cm(2)s. The maximum room temperature QE was 32% at 900 nm excitation. At cryogenic temperatures the FWHM reached 850 nm with 974 nm excitation and we observed two new bismuth emission bands at 2000 and 2600 nm. The QE reached 40% for both 974 and 808 nm excitation at cryogenic temperatures. Emission spectra, normalized to the excitation power, taken with excitation wavelengths of 480-1300 nm, revealed 4 absorption bands at 680, 850, 1020 and 1180 nm. The 1180 nm absorption band was previously unobserved. Deconvolution of the emission spectra into Gaussians indicated 5 distinct emission bands over the entire excitation range. The maximum room and cryogenic temperature lifetimes were 175 and 280 mu s, respectively. Their respective emission and excitation wavelengths were similar to 1500 and 974 nm; and similar to 1600 and 808 nm. By examining previously published models of Bi emission in glasses to see if they could account for the 2000 and 2600 nm emission bands, and reviewing other previously published evidence, we propose that the origin of the emission in Bi:GLS is Bi(2) (2-) dimers.

  • Dispersion controlled tellurite microstructured fibers for supercontiuum generations pumped by picosecond and femtosecond fiber lasers 査読

    Supercontinuum (SC) generation has the important applications such as broadband light source, optical coherence tomography, ultra-short pulse compression, and optical frequency metrology, etc. Tellurite glass is transparent in the mid-infrared range, and has a higher n(2) than silica glass by at least one order of magnitude. We have fabricated the hexagonally shaped tellurite air-clad fiber with a core diameter of around 1 mu m through controlling the temperature field exactly in the process of fiber-drawing. Since the SC generation strongly depends on the chromatic dispersion, which is determined by the microstructure of fiber, it is interesting to investigate and demonstrate such dependence for such a small core fiber in detail. In this work by pumping a positive pressure of nitrogen gas into the holes of preform, we obtained 1 mu m core fibers with diameter ratio of holey region to core (DRHC) varied from 3.5 to 20. The dispersion was tailored effectively by the variation of DRHC. Dependences of SC on the microstructure and dispersion were demonstrated. The pump lasers were picosecond and femtosecond fiber lasers. One octave flattened SC generation was obtained for the fibers pumped by 1064 nm picosecond fiber laser with the pulse energy of several hundred pJ. Intense second and third harmonic generations were obtained under the pump of a 1557 nm femtosecond fiber laser. The correlation of dispersion and SC spectra was analyzed. Such tellurite microstructured optical fibers (MOFs) with high nonlinearity and controlled dispersion are significant in nonlinear applications.

    The aim of this paper is to present an overview of the recent achievements of our group in the fabrication and optical characterizations of As2S3 microstructured optical fibers (MOFs). Firstly, we study the synthesis of high purity arsenic sulfide glasses. Then we describe the use of a versatile process using mechanical drilling for the preparation of preforms and then the drawing of MOFs including suspended core fibers. Low losses MOFs are obtained by this way, with background level of losses reaching less than 0.5 dB/m. Optical characterizations of these fibers are then reported, especially dispersion measurements. The feasibility of all-optical regeneration based on a Mamyshev regenerator is investigated, and the generation of a broadband spectrum between 1 mu m and 2.6 mu m by femto second pumping around 1.5 mu m is presented.

    We present the design, dispersion calculations and tailoring, and simulation of the parametric gain in the composite tellurite-fluorophosphate glass fiber. The fiber has the tellurite core subsequently surrounded by fluorophosphate and tellurite claddings. Thermal properties of the tellurite and fluorophosphate glasses match, depicting the feasibility of the fabrication of the fiber under controlled environment. The composite fiber introduced here has the advantage of easy handling over the fiber tapers or the air cladding tellurite nanofibers. With our analysis we observe that the fluorophosphate and the tellurite cladding thickness along-with the fiber core diameter, have control on the dispersion and the parametric gain. The wavelength band, over which the dispersion is anomalous, increases with increasing tellurite core diameter. For longer wavelengths, increasing the fluorophosphate cladding thickness causes increase in the anomalous dispersion bandwidth and further flattening of the dispersion curve. The slope of the dispersion curve near the zero dispersion wavelength (ZDWL) is greatly reduced for thicker outer tellurite ring claddings. It is possible to design zero flattened dispersion fiber or the fiber providing two ZDWLs in the communication band, which can generate broadband parametric amplification. The gain obtained has strong bandwidth dependence on the dispersion slope. We study the effects of the fiber length, pump power, and pump detuning from the ZDWL, on the parametric amplification. With multiple pumping with proper selection of the pump wavelengths, the parametric amplification process can generate ultra flat, broadband amplifiers as the dispersion provided by the composite fiber is anomalous over a wide bandwidth.

    We propose a chalcogenide (As(2)S(3)) core tellurite cladding microstructured fiber with flattened normal dispersion for ultraflat supercontinuum (SC) generation. To realize flattened normal dispersion, the structure parameters are optimized such as the chalcogenide core diameter, the air hole diameter and the distance between the centers of the two neighboring air holes. The ultraflat normal dispersion curve is obtained and the pulse propagation is investigated using a nonlinear Schrodinger equation. It is shown that an ultraflat SC spectrum with deviations less than 4 dB over an octave (from 1400 nm to 3000 nm) can be achieved by the illumination of a pulsed light with a pulse width of 200 fs, central wavelength of 2000 nm and peak power of 1000 W.

    We report broad near-infrared soliton and associated dispersive wave source generation (1228-1867 nm) and tunable green third harmonic generation (528-542 nm) by LP(11) mode excitation in a few-mode tellurite microstructure fiber pumped by a 1557 nm femtosecond fiber laser. The fiber presents a wide range of wavelengths in which the fundamental mode experiences normal dispersion, whereas the higher-order modes propagate in the anomalous dispersion regime. LP(01) or LP(11) mode can be selectively excited, and obviously different spectra are obtained based on the different mechanisms of supercontinuum generation. (C) 2009 American Institute of Physics.

    We report what we believe to be the first demonstration of supercontinuum generation spanning over three octaves from UV (at least similar to 350 nm) to 3.85 mu m in a 2.5-cm-long fluoride fiber pumped by a 1,450 nm femtosecond laser. The spectral broadening in the fluoride fiber is caused primarily by self-phase modulation. Its performance is also compared with that of a 2.5-cm-long silica fiber pumped by the same laser.

    Tb3+-Yb3+ codoped fluorophosphate glasses were synthesized and properties of the visible emission at 0.54 mu m were investigated. The upconversion excitation efficiency from Yb3+ to Tb3+ was studied by evaluation of the cooperative energy transfer efficiency from Yb3+ to Tb3+ (eta(CET)) and the back-transfer efficiency from Tb3+ to Yb3+(eta(BT)), which gave a positive and negative contribution to upconversion excitation, respectively. The eta(CET) was as high as 30% and the eta(BT) was less than 1% in the fluorophosphate glass. This indicates that Tb3+-Yb3+ codoped fluorophosphate glass is promising as laser and gain medium in the 0.54 mu m band.

    Relaxation of 1.54 mu m emission of the erbium doped borosilicate glasses with high rare earth solubility was investigated. When the erbium content is less than 0.2 wt%. multi-phonon relaxation is the predominant process of non-radiative relaxation. It is difficult to increase the quantum efficiency higher than 70% for erbium ions in this glass clue to multi-phonon relaxation. Because of the good glass-formation ability and high rare earth solubility, this glass will be suitable as a host for rare earth ions with a large energy gap, such as Yb3+, Eu3+ or Tb3+.

    We present the design of the chalcogenide (As2S3) glass nanofibers with the nonlinear tellurite glass as the cladding material. Both of these glasses have high nonlinearity. We show that the simple step index structure with tellurite cladding has the normal dispersion in the telecommunication window for any value of the core diameter, ranging from the sub-wavelength size to a few micro-meters. The dispersion achieved is flat so as to be applicable to dispersion compensating devices. However, the dispersion can not be tailored to zero. So we propose the photonic crystal fiber (PCF) structure, which has six circular identical air holes introduced in the tellurite cladding around the chalcogenide core. The air holes introduced cause the decrease in the effective cladding index. This structure shows anomalous dispersion in the telecommunication band with two zero dispersion wavelengths. With further optimization the structure can show zero flattened dispersion. We study the effect of the various design parameters - the chalcogenide core diameter, the air hole diameter, and the pitch, that is the distance between the centers of two neighbouring air holes, which is same as the distance between the center of the core and any of the air holes. We optimize the design to achieve zero slope (flattened) at the zero dispersion wavelength, 1.55 mu m. The thermal characteristics of tellurite glass match with the chalcogenide making the fabrication of the chalcogenide core PCF with the tellurite glass as a cladding material feasible. We also present the calculation of the nonlinearity of the PCF.

    The spectroscopic properties of Tb(3+)-doped borosilicate glasses are investigated to assess their potential as gain media in the 0.54 mu m band. Analysis of the concentration and temperature dependences of the optical transitions from the (5)D(4) level of Tb(3+) is carried out. The emission lifetime of the (5)D(4) level at 300 K is found to be 2.61 +/- 0.03 ms, and almost invariant for Tb(3+) concentrations less than 15 wt% (1.68x10(21) ions/cm(3)). Judd-Ofelt analysis is used to calculate the emission transition probabilities from the (5)D(4) level and the emission cross section at 300 K for the (5)D(4) -&gt; (7)F(5) transition was 8.1 x 10(-22) cm(2) at 541 nm. Temperature dependent non-radiative relaxation of the (5)D(4) level is observed in samples with 5 and 20 wt% Tb(3+). The quenching process of the (5)D(4) level in the temperature range of 50 similar to 373 K is thought to be caused by a two-photon one-site resonant process, whereas it is dominated by a two-site non-resonant process at temperatures below 40 K. Our results indicate that Tb(3+)-doped borosilicate glass is a promising candidate for optical gain media in the green (0.54 mu m) band

    In this paper, we investigate simultaneous 853 nm + 1533 rim amplification, and wavelength conversion between 1533 nm and 853 nm in Er3+-doped fluoride fiber. Based on our simulation results, simultaneous 853 nm (4S(3/2)-&gt; 4I(13/2) transition) + 1533 nm (4I(13/2)-&gt; 4I(15/2) transition) amplification, and wavelength conversion between 1533 nm and 853 nm can be realized in Er3+-doped fluoride fibers with the excitation of a 974 nm laser diode, respectively. Furthermore, we investigate the interactions between 853 nm and 1533 nm amplifications, and discuss their effects on simultaneously 853 rim + 1533 nm amplifier. The crosstalk between 853 nm and 1533 nm signals is very weak because of relatively long lifetime (similar to 10 ms) of the 4I(13/2) level. By introducing a cavity for 853 nm or 1533 nm lasing into the system, the possibility of wavelength conversion from 1533 nm to 853 nm or from 853 nm to 1533 nm in Er3+-doped fluoride fiber excited at 974 rim is clarified, which can be used as the wavelength converter or optical switch between public (the third window: similar to 1533 nm) and local (the first window: similar to 853 nm) networks in future networks.

    Transparent Tb3+ and Yb3+ codoped oxyfluoride glass ceramics containing CaF2 nanocrystals were prepared by melt quenching and subsequent heat treatment. Crystallization kinetics of CaF2 nanocrystals was investigated by differential scanning calorimetric method. The average apparent activation energy E-a of the crystallization was similar to 498 kJ/mol. Moreover, the value of the Avrami exponent n was 1.01. These results suggest that the crystallization mechanism of CaF2 is a diffusion controlled growth process of needles and plates of finite long dimensions. X-ray diffraction patterns and transmission electron microscopy image confirmed the CaF2 nanocrystals in the glass ceramic. Ultraviolet (UV) and visible emission spectra of the as-made glass and the glass ceramic with an excitation of a 974 nm laser diode were recorded at room temperature. An intense UV emission at 381 nm was observed in the glass ceramic. The origin of the enhancement of the emission at 381 nm was investigated using spectroscopic technique and Judd-Ofelt analysis. The enhancement of the emission at 381 nm could be attributed to the change of the ligand field of Tb3+ ions due to the incorporation of some Tb3+ and Yb3+ ions into CaF2 nanocrystals in the glass ceramic.

    In this study, we investigated the performance of slow light generation via SBS or SRS in tellurite glass based on characterization of Raman and Brillouin gain coefficients and an evaluation method of slow light generation we developed. The effects of different heavy metal oxides additions on slow light generation via SRS in tellurite glass are also discussed. Our results show that designed tellurite glass is a promising candidate for slow light generation via SBS or SRS due to its high Raman and Brillouin gain coefficients.

    We systematically added WO3 (UP to 10 mol%) and P2O5 (up to 16 mol%) in Teo(2) BaO-SrO-Nb2O5 (TBSN) glass system and studied thermal and optical properties of the resultant glasses. The dependences of the additive concentration on glass transition (T-g) and crystallization (T-x) temperatures are presented. The TBSN glass added with &gt;= 4 mol% WO3 and PA showed high stability against crystallization. The changes in optical band gap energy due to WO3 and P2O5 addition was studied using UV-VIS-NIR absorption spectrometry. The WO3 addition shifted the optical band gap to longer wavelengths, whereas P2O5 addition shifted that to shorter wavelengths. Effects of the WO3 and P2O5 addition on the Raman spectra of' TBSN glass are clarified. New Raman bands due to WO4 and PO4 tetrahedra formed in the resultant glasses broadened their Raman spectra. Present glasses are characterized by higher thermal stability and wider Raman spectra, therefore, they are promising candidates for fiber Raman amplifiers in photonics systems. (c) 2006 Elsevier B.V.

    New tellurite-based glasses as broadband Raman gain media are developed to realize high performance fiber Raman amplifiers. These performances are achieved by WO3 and P2O5 doping in TeO2-BaO-SrO-Nb2O5 (TBSN) glass. The maximum gain coefficient obtained in the present study was similar to 50 times that of silica glass for 532 nm excitation. The bandwidth (i.e., full width at half maximum) of these doped glasses was more than twice that of a conventional tellurite-based glass and 70% larger than that of silica glass.

    Phospho-tellurite glasses containing heavy metal oxides and alkaline earth oxides have been fabricated. The presence of BaO and SrO in the glasses remarkably increased their thermal stabilities. These glasses have thermal stabilities as high as 224 °C, which make them suitable for various fiber devices applications. The corrected relative Raman intensities (I COrr) and scattering cross sections (σCOrr) of various peaks for all the glasses are compared with respect to silica. These glasses show superior relative Raman cross sections than silica and conventional tellurite glasses, the most widely studied for fiber devices applications (TeO2-ZnO-Li2O-Bi2O3, TZLB). The gain bandwidth is also an important parameter apart from the Raman gain coefficient in selecting a material for Raman amplifiers. The bandwidth broadening effect can be estimated based on σCOrr/I corr as σCOrr is proportional to the Raman scattering intensity and broadness of the spectrum. For simplicity the broadness of the bandwidth of the present glasses are also judged by the normalized bandwidth with respect to silica (i.e. bandwidth of sample/bandwidth of silica). It is 1.55 for one of the representative phospho-tellurite glasses and 0.75 for TZLB. The presence of heavy metal oxides and alkaline earth oxides makes the Raman bands due to TeO2 and P2O5 continuous and one such glass has continuous Raman bandwidths exceeding 700 cm ·1. Thus, these glasses could be potential candidates for ultra-broadband fiber Raman amplifiers.

    New quaternary glasses in the systems TeO2-BaO-SrO-Nb 2O5 and TeO2-BaO-SrO-Ta2O 5 are prepared, and are found to have improved thermal stabilities and refractive indices, making them suitable for photonics device applications. Systematic Raman spectroscopic studies of these glasses are undertaken to unravel the presence of various structural units, and the contributions made by them with varying modifier oxides contents have been quantified. A comparative study is made on the evolution of various structural units with the addition of modifier oxides in the two glass systems. The Raman bandwidths of these glasses are broader compared to conventional tellurite glasses. Both glass systems show an additional Raman band beyond 870 cm-1 that is not present in other tellurite glass systems. The Nb-O related vibrational band near 870 cm -1 is stronger than the band around 900 cm-1 in the Ta2O5 containing glasses. The coordination geometry of tellurium atoms in the presence of Nb2O5 and Ta 2O5 is discussed with the help of molecular modelling results.

    A transparent glass-ceramic containing borate crystallites in tellurite glass is reported. Controlled heat treatment resulted in surface crystallization of BaB4O7 in the BaO-B2O3-TeO 2 glass system. The second-order optical nonlinearities observed in these surface crystallized glasses were attributed to the distortion present in the BaB4O7 unit cell as evidenced by x-ray powder diffraction studies. A d33 value of 0.08 pm/V was obtained from the Maker fringe analysis for a surface crystallized glass. © 2004 American Institute of Physics.

    We investigate the characteristics of optical modes in a new designed hollow-core photonic crystal fiber (PCF) with large modal separation. The large effective refractive index difference between the adjacent second-order vector modes can be maintained higher than 0.001 within the wavelength range from 1 to 2 μm. The maximum value can arrive 0.01199 between HE21 and TM01 mode at 2 μm. The fundamental mode of the proposed PCF has flat dispersion in a wide spectral range, which can be applied on wideband supercontinuum generation. The influence on the characteristics by the PCF structure has also been investigated. The increase of the size of the central air hole and the duty cycle affects the flatness of the dispersion curve to some extent. Our simulated results could provide an optimized fiber structure for the experimental study on stable transmission of vector modes.
