拉锥Ge_(15)Sb_(20)Se_(65)硫系玻璃光纤对乙醇溶液检测的光谱分析研究
|
摘要
采用熔融淬冷法制备了Ge_(15)Sb_(20)Se_(65)硫系玻璃,并拉制成直径为500μm的裸玻璃光纤,损耗测量结果显示光纤在6μm波长处的最低损耗为1.68dB/m。利用自行搭建的自动光纤拉锥平台拉制了腰锥直径分别为20,100,250μm的拉锥光纤,并对不同浓度的乙醇溶液进行了光谱分析检测实验,最后基于光纤倏逝波理论用COMSOL Multi physics软件仿真了三种不同腰锥直径的锥形光纤对乙醇溶液的传感灵敏特性,与实验结果进行了对比。
In this work,Ge_(15)Sb_(20)Se_(65) glass is synthesized by the melt-quenching method and then drawn into a bare glass fiber with a diameter of 500μm.The minimum transmission loss of this fiber is about 1.68 dB/m at the wavelength of 6μm.A homemade tapering platform allows to taper the chalcogenide fibers into different waist diameters of 20,100 and 250μm,respectively.The spectroscopic analysis of the tapered fibers in ethanol solution with different concentrations is presented.Based on the theory of fiber evanescent wave,the sensing characteristics of the tapered fiber in the ethanol solution are simulated by COMSOL Multiphysics software.The results of simulation and experiment are compared and discussed.
