Paper Abstract

In this paper, a pressure sensor based on high-birefringence fiber loop mirror (HiBi-FLM) is proposed and demonstrated. The high-birefringence fiber is pasted to an inflated, elastic, ring shaped rubber gasbag and served as a sensitive probe. When outside pressure changes, the volume of the gas in the ring rubber gasbag changes and it makes the strength of the high-birefringence fiber variety. The relationship between shift of the resonant wavelength (peak wavelength) and pressure is discussed and experimentally researched. Experimental results show that the sensitivity is 1.63×10-3nm/Pa. The sensor has many advantages such as high sensitivity, polarization independent, easy manufacture, low cost.
