| 摘 要： | 设计制作了一种基于马赫-曾德干涉结构的传感器用于折射率和温度的同时测量，传感器的结构为单模-多模-细芯-多模-单模。利用RSoft光学仿真软件的BeamPROP模块对传感结构内部光场进行模拟分析，确定了多模光纤(multi-mode fiber, MMF)及细芯光纤(thin core fiber, TCF)的最优长度，制作了传感结构并搭建实验系统观测其折射率和温度响应情况，结合敏感矩阵，实现了双参量的同时测量。实验结果表明，该传感器在1.333—1.380的折射率范围内灵敏度为-44.944 nm/RIU,在30—65℃的温度范围内灵敏度为0.082 9 nm/℃。本文提出的传感器结构简单、体积小、灵敏度高，可以为折射率和温度双参量传感设计提供参考。
