Abstract

In this paper we report on polarimetric distributed Bragg reflector fiber laser sensor for hydrostatic pressure. Three different types of active fibers were used to fabricate dual-polarization distributed-Bragg-reflector fiber lasers and their responses to hydrostatic pressure were characterized. Three fibers shown different beat frequency response to hydrostatic pressure and a maximum pressure sensitivity of 2.28 MHz/Mpa was obtained. By detecting the double frequency signal, the sensitivity can be further increased to 4.56 MHz/MPa. We also tested the long term stability of the sensor at 300oC.
