Abstract
A fiber optic temperature sensor realized by low-birefringence photonic crystal fiber (PCF) based Sagnac loop is demonstrated. Due to the low birefringence of this PCF, only one dip appears in the spectrum when an amplified spontaneous emission (ASE) light source is used. The sensitivity of the temperature measurement of -0.123nm/°C is achieved in the range of 25°C-85°C, and the temperature resolution limited by the 20pm wavelength resolution of the OSA is about 0.16°C.
