Paper Abstract

A high sensitivity and low cost all-fiber temperature sensor combined a single-mode-polarization maintaining-single-mode optical fiber (SPS) structure and a Sagnac loop is proposed and experimentally demonstrated. In this sensor, the SPS structure is reeled into a circle is inserted into a Sagnac loop. Experimental results show that the radius of the circle has significant influence on temperature sensitivity. The temperature sensitivity can reach up to 1.678nm/°C for the radius of 3cm.
