摘要

利用准分子激光器在普通单模光纤上加工微孔, 制作了一种微孔结构型的光纤Fabry-Perot(FP)腔, 并对该微孔型光纤FP腔的温度特性进行了理论和实验研究。研究表明, 当外界环境温度变化时, FP腔腔长和腔中介质的折射率会发生变化, 致使传感器输出光谱发生漂移。通过观测光谱对应的峰值或谷值的漂移量, 即可实现对环境温度的传感检测。实验结果发现, 随着温度的升高, 波长逐渐向短波方向方发生漂移, 且波长的漂移量温度变化呈线性关系, 其对应的温度灵敏度和线性度分别为-0.152 nm/℃和98.8%。该微孔结构型光纤F-P腔温度传感器具有结构简单、成本低廉、实用性好等优点, 可以适应不同温度的需要, 研究结果可为该种器件在传感中的应用提供一定参考。

Abstract

A micro-hole structure fiber Fabry-Perot (FP) cavity is fabricated using an excimer laser to process a micro-hole in single mode fiber (SMF). And the theoretical and experimental research of temperature response characteristics of the FP cavity is performed. Research results show that when the temperature of external environment changes, the FP cavity length and the refractive index of medium in the cavity will change, which will lead to sensor output spectrum shifting. By observing the shifting of the peak or valley values of spectrum, the sensing inspection of environment temperature can be realized. Experimental results show that spectrum shifts to short wavelength gradually with the increasing of temperature. The wavelength shifting is linear with the temperature changing, and the corresponding temperature sensitivity and linearity are -0.152 nm/℃ and 98.8% respectively. The micro-hole structure fiber FP temperature sensor has the advantages of simple structure, low cost and good practicability, and it can meet the needs of different temperatures. The research results can provide a reference for the application of this device in sensing.
