摘要：

The polymer coating on the surface of traditional optical fiber would deform and melt at high temperature. Metal coating which could maintain its shape in a large temperature scale is one solution to this problem. In this work, we experimentally investigated the temperature sensing performances based on an aluminized panda polarization maintaining fiber (APPMF) and a fiber Bragg grating (FBG) in Sagnac loop in a large temperature scale. Modeling simulation of APPMF proved that its birefringence was influenced by temperature and it could be used as the temperature-sensing probe in an SI. FBG was used to mark the dip wavelength in SI when the movement of dip wavelength exceeded a free spectral range (FSR). Experimental results showed that the maximum sensitivity reached 0.818 nm/degrees C for a 12 cm long APPMF, while increased to 1.011 nm/degrees C as the length of APPMF decreased to 2 cm. The aluminum coating enhanced the ductility of the fiber and made the fiber suitable for high-temperature measurement. The proposed APPMF also experienced a degradation because of germanium diffusion in fiber core very high temperature which made the sensor suitable for very high temperature sensing in a short time. This work provides a useful attempt for exploring high-temperature fiber interferometric sensing.
