Paper Abstract

A temperature sensor based on polarization non-reciprocity in fiber Sagnac interferometer was proposed and investigated theoretically and experimentally. Special signal detection schemes were proposed and an experimental system with an all polarization configuration was setup. The temperature measurement experiment was done within -40°C ~ +60 °C range and the stability were investigated at absolute 0 °C in mixture of ice and water respectively. The result agrees with theory well and good performance has been obtained with parameters optimized. Discussion shows that this kind of temperature sensor can achieve high precision and has great application potential.
