摘要

高折射率棒光子带隙光纤受高折射率填充材料的影响很大

对温度、外加电场等参数非常敏感。为获得高灵敏度的光子晶体光纤温度传感

提出了在其包层空气孔注入温敏液体的方法

并利用全矢量有限元法对提出的方法进行了仿真。仿真结果表明

随着温度的升高

光纤的有效折射率减小

模场面积增大

温度灵敏度能达到20.2dB/m/℃。

Abstract

Highly influenced by filler materials with high refractive index

PBG fibers with high-index rods are very sensitive to such parameters as temperature and applied electric field.In order to obtain temperature sensing of photonic crystal fibers with high sensitivity

we propose a method

in which temperature-sensitive liquid is injected into the air holes of their claddings

and simulate the method by using the full vector finite element method.The results indicate that with the increase of temperature

the effective refractive index decreases

the mode field area increases

and the temperature sensitivity can be as high as 20.2dB/m/℃.
