| 4 | Additive Manufacturing Fiber Preforms for Structured Silica Fibers with Bismuth and Erbium Dopants显示文摘Dear Editor Silica optical fibers have attracted a lot of attention because they are widely used in communications and sensing,and forming today’s internet backbone.Driving much of the Internet-of-Things(IoT)evolution,optical fibers are expanding from a single function transmission technology to perform multiple functions and a growing need for various custom-design application-specific optical fibers.Current optical fiber manufacturing based on chemical vapor deposition(CVD)technologies together with stack-and-draw approaches used for structured optical fibers faces numerous challenges in enabling more complex geometries multimaterial composite fibers and multicore fibers.The additive manufacturing,or 3D printing,offers a solution to address all those challenges,and may potentially disrupt the optical fibers fabrication and bring in an evolution to IoT. | Yushi Chu Xinghu Fu Yanhua Luo John Canning Jiaying Wang Jing Ren Jianzhong Zhang Gang-Ding Peng | 2022 | Light(Advanced Manufacturing)2022，3，2： | 0 |
| 5 | A grapefruit microstructure fiber temperature sensor coated with liquid crystal based on waist-enlarged taper显示文摘In this paper, a grapefruit microstructure fiber(GMF) temperature sensor coated with liquid crystal(LC) based on waist-enlarged taper is proposed and fabricated, and its temperature sensing characteristics are analyzed. The waist-enlarged taper is formed at the fusion point between single mode fiber(SMF) and GMF. The capillary glass tube is sleeved outside GMF, LC is filled into the capillary glass tube, and its two ends are finally sealed to form a sensor. The experimental results show that when the length of GMF is 2.5 cm, the temperature sensitivity of the sensor can reach up to 195.3 pm/℃ in the range of 30-90℃, and it has a good stability for reuse. Thereby, it can be used in biochemical, industrial production and other temperature detection areas. | WANG Feng LI Jiaxuan ZHANG Rongjing FU Xinghu | 2024 | Optoelectronics Letters2024，20，3： | 0 |
| 6 | Brillouin scattering spectrum character extraction based on genetic algorithm and seeker optimization algorithm显示文摘A new hybrid optimization method based on genetic algorithm(GA)and seeker optimization algorithm(SOA)is presented in this paper.The hybrid algorithm optimizes SOA by using crossover and mutation operations in GA in order to improve the global search ability of SOA.Four algorithms,i.e.particle swarm optimization(PSO),SOA,GA and quantum-behaved particle swarm optimization(GA-QPSO)and GA-SOA are used to process the simulation and experimental data of Brillouin scattering spectrum(BSS)at different temperatures.The results show that GA-SOA improves the accuracy of extracting the center frequency shift and the minimum center frequency of Brillouin scattering spectrum compared with other three algorithms.The shift error is 0.203 MHz.Therefore,GA-SOA can be applied to the accurate extraction of BSS characteristics. | 张燕君 Jin Peijun Fu Xinghu Hou Jiaoru Zhang Fangcao Xu Jinrui | 2019 | High Technology Letters2019，25，4： | 0 |
