A high sensitivity temperature sensor based on a selectively filled photonic crystal fiber sagnac interferometer
Abstract
A high sensitivity temperature sensor based on a Sagnac interferometer consisting of a segment of selectively liquid-filled photonic crystal fiber (SLF-PCF) is proposed and demonstrated. The SLF-PCF is achieved by the high frequency CO 2 laser and possesses unique birefringence feature. Numerical and experimental results are presented, and a high sensitivity temperature sensor with sensitivity of ~-11.6 nm/°C is achieved from 65°C to 85°C.
