4Recent Advances in Spectroscopic Gas Sensing With Micro/Nano-Structured Optical Fibers显示文摘With micro-and nano-structured optical fibers,parts-per-million to parts-per-trillion level gas detection has been demonstrated for a range of gases such as methane,acetylene,ethane,carbon monoxide,hydrogen,and oxygen.We review the recent development in optical fiber gas cells and gas detection systems based on direct absorption,photothermal,photoacoustic,and stimulated Raman spectroscopies.Wei JIN Haihong BAO Pengcheng ZHAO Yan ZHAO Yun QI Chao WANG Hoi Lut HO 2021Photonic Sensors2021,11,2:1
5Mid-infrared all-optical modulators based on an acetylene-filled hollow-core fiber显示文摘We report all-optical mid-infrared phase and intensity modulators based on the photo-thermal effect in an acetylene-filled anti-resonant hollow-core fiber.Optical absorption of the control beam promotes the gas molecules to a higher energy level,which induces localized heating through non-radiative relaxation and modulates the refractive index of the gas material and hence the accumulated phase of the signal beam propagating through the hollow-core fiber.By modulating the intensity of the control beam,the phase of the signal beam is modulated accordingly.By use of a 1.53μm near-infrared control beam,all-optical phase modulation up to 2.2πrad is experimentally demonstrated at the signal wavelength of 3.35μm.With the phase modulator placed in one arm of a Mach-Zehnder interferometer,intensity modulation with on-off ratio of 25 dB is achieved.The gas-filled hollow-core-fiber modulators could operate over an ultra-broad wavelength band from near-to mid-infrared and have promising application in mid-infrared photonic systems.Kaiyuan Zheng Shoulin Jiang Feifan Chen Yan Zhao Shoufei Gao Yingying Wang Hoi Lut Ho Wei Jin 2022Light(Advanced Manufacturing)2022,3,4:0
6Broadband all-fiber optical phase modulator based on photo-thermal effect in a gas-filled hollow-core fiber显示文摘We report broadband all-fiber optical phase modulation based on the photo-thermal effect in a gas-filled hollow-core fiber.The phase modulation dynamics are studied by multi-physics simulation.A phase modulator is fabricated using a 5.6-cm-long anti-resonant hollow-core fiber with pure acetylene filling.It has a half-wave optical power of 289 mW at 100 kHz and an average insertion loss 0.6 dB over a broad wavelength range from 1450 to 1650 nm.The rise and fall time constants are 3.5 and 3.7μs,respectively,2–3 orders of magnitude better than the previously reported microfiber-based photo-thermal phase modulators.The gas-filled hollow-core waveguide configuration is promising for optical phase modulation from ultraviolet to mid-infrared which is challenging to achieve with solid optical fibers.Shoulin Jiang Feifan Chen Yan Zhao Shoufei Gao Yingying Wang Hoi Lut Ho Wei Jin 2023Opto-Electronic Advances2023,6,5:0
