提出了一种简单的基于单模光纤的本征法布里-珀罗干涉仪（FPI），利用电弧放电形成薄膜作为FPI腔的一面反射镜。的温度和折射率（RI）的建议设备的特性进行了研究。实验结果表明，该装置可以提供与温度无关的测量RI的条纹对比灵敏度为~72.59 dB/RIU（RI单位）。同时，它也可以用作温度传感器，波长灵敏度为~8 pm/°C。因此，通过分别检测条纹对比度和波长的变化，可以实现折射率和温度的同时测量。
We propose a simple intrinsic Fabry-Perot interferometer (FPI) based on single-mode fiber, where a thin film is formed by arc discharge to serve as one mirror of the FPI cavity. The temperature and refractive-index (RI) characteristics of the proposed device are investigated. Experimental results show that the device can provide temperature-independent measurement of RI with a fringe-contrast sensitivity of ~72.59 dB/RIU (RI units). Meanwhile, it can also be used as a temperature sensor with a wavelength sensitivity of ~8 pm/°C. Therefore, the potential simultaneous measurement of RI and temperature could be realized by detecting the variations of fringe contrast and wavelength, respectively.
