Temperature measurement of an isopropanol-immersed microbottle resonator is demonstrated. The theoretical analysis indicates that the resonance wavelength blue shifts as the increase of temperature, and the temperature sensitivity increases with the decrease of resonator dimension, which are also demonstrated by experimental results. The temperature sensitivity enhancement of up to 4.6 times relative to the sensor in the air is achieved, which could be benefit from the high thermal refraction coefficient of isopropanol. Furthermore, a robust package has also been proposed to make the present sensor more practically.

基于浸没在异丙醇中的微瓶谐振器的温度传感器

展示了浸入异丙醇的微瓶谐振器的温度测量。理论分析表明，谐振波长随着温度的升高发生蓝移，温度灵敏度随着谐振腔尺寸的减小而增加，实验结果也证明了这一点。相对于空气中的传感器，温度灵敏度提高了 4.6 倍，这可能得益于异丙醇的高热折射系数。此外，还提出了一种坚固的封装，以使本传感器更实用。
