A low-index polymer-overlaid micro-resonator (LIMR) with high sensitivity is investigated for simultaneous temperature and ambient refractive index (ARI) measurement. The sensitivity of the proposed LIMR to the ambient index is remarkably enhanced at the turning points of the dispersion curve. After examining the optical spectrum of the proposed LIMR sensor, we assess two typical configurations formed at the output of the fiber, fast-varying resonator (FVR) and slow-varying interferometer (SVI). The dual parameter sensing probe measures simultaneously, showing a presentation of temperature and ARI with the experimental sensing proportions of 0.30 nm/°C and 304 nm/RIU to FVR, 1.16 nm/°C and 1874 nm/RIU analogously to SVI. Therefore, it is possible to successfully discriminate temperature and ARI sensitivities by measuring different wavelength shifts of the proposed LIMR based on calculated dispersion curve.

基于色散关系的低折射率聚合物叠加微谐振器双参数传感器

研究了一种具有高灵敏度的低折射率聚合物覆盖微谐振器 (LIMR)，用于同时测量温度和环境折射率 (ARI)。所提出的 LIMR 对环境指数的敏感性在色散曲线的转折点显着增强。在检查了所提出的 LIMR 传感器的光谱后，我们评估了在光纤输出端形成的两种典型配置，即快变谐振器 (FVR) 和慢变干涉仪 (SVI)。双参数传感探头同时测量，显示温度和 ARI 的呈现，实验传感比例为 0.30 nm/°C 和 304 nm/RIU 到 FVR，1.16 nm/°C 和 1874 nm/RIU 与 SVI 类似。所以，
