摘要

提出了一种基于八角形几何结构空心光子晶体光纤的气体传感器。利用COMSOL Multiphysics软件，采用全矢量有限元方法对所提出的PCF的光学特性进行了数值研究。对空心PCF的八角形晶格进行了优化，获得了较好的相对灵敏度和较低的约束损耗。在甲烷(CH4)的吸收线1.67µm波长处，我们获得了最大相对灵敏度约为97%，最小约束损失约为0.007 dB/m。

Gas sensor based on octagonal hollow core photonic crystal Fiber

This paper presents a gas sensor based on octagonal geometric structured hollow core photonic crystal Fiber. We have studied the optical properties of the proposed PCF numerically by full vector finite element method (FEM) using COMSOL Multiphysics. The octagonal lattice of the hollow core PCF has been optimized to obtain better relative sensitivity and low confinement loss. We have acquired the maximum relative sensitivity of around 97% and minimum confinement loss of ∼0.007 dB/m at 1.67 µm wavelength which is the absorption line of methane (CH4).
