摘要

通过改变温敏液体种类和液体填充方式

研究了基于混合晶格的高双折射光子晶体光纤(PCF)的温敏特性。使用基于有限元法的Comsol软件仿真分析了光纤双折射特性随温度的变化关系。研究结果表明

选择不同的温敏液体和采用不同的液体填充方式都会对PCF的温敏特性产生不同程度的影响。若使用乙醇液体进行纤芯区域圆形空气孔填充

工作在1 550 nm的PCF的温度灵敏度可达2.5×10

-5

/℃。与相关的PCF结构相比

本文提出的PCF结构和新的温敏液体填充方式可以更好地提升PCF的温度灵敏度

在PCF温度传感领域很有应用前景。

Abstract

By using different methods to fill different types of thermo sensitive liquids

the thermo sensitive characteristics of a high birefringent Photonic Crystal Fiber(PCF) based on hybrid lattices was researched. The relationship of birefringence properties and temperature was investigated using Comsol software in finite element method. The numerical results show that the thermo sensitive characteristics of the PCF are influenced by liquid types and filling methods. When the ethanol is filled in the circular air holes in a core area

the sensitivity of the PCF worked at an excitation wavelength of 1 550 nm is up to 2.5×10

-5

/℃ with pitch of holes in 1 μm

the diameter of a circular air hole in 0.96 μm and the aspect ratio of rectangular air holes in 4. As compared with that of corresponding PCF structures

the fiber proposed and liquid filling method have higher thermo sensitivity and broader application prospects for high sensitivity temperature sensors.
