摘要
提出一种反射型法布里-珀罗(FP)标准具和微环谐振腔级联的温度传感器。该温度传感器由光纤反射镜、FP标准具和微环谐振腔构成。利用强度探测的方法,仿真计算和实验验证表明,温度传感器具有较高的灵敏度和较低的探测极限。将宽带光源和滤波器组合作为实验的输入光源,反射型FP标准具起到滤波的作用,温度传感元件是微环谐振腔。仿真计算得出该温度传感器的灵敏度为2.1406 dB/℃。实验结果表明,该温度传感器的灵敏度为1.9434 dB/℃,探测极限为0.01℃。
A temperature sensor cascading a reflective Fabry-Perot(FP) etalon with a microring resonator is proposed.This temperature sensor is composed of a fiber mirror, an FP etalon, and a microring resonator. The intensity interrogation method is employed, and both the simulation calculation and experimental verification results show that the proposed temperature sensor offers high sensitivity and a low detection limit. A combination of a broadband light source and a filter is used as the input light source for the experiment. The reflective FP etalon plays the role of a filter, and the temperature sensing element is the microring resonator. The sensitivity of the proposed temperature sensor yielded by the simulation calculation is 2. 1406 dB/℃. The experimental results show that the sensitivity of the temperature sensor is 1. 9434 dB/℃, and its detection limit is 0. 01 ℃.
