Paper Abstract

In this paper, a pressure sensor based on distributed Bragg reflector (DBR) fiber laser was reported. The laser was operated in single longitudinal mode. For the longitudinal-mode has two orthogonal polarizations, external press on the cavity would induce birefringence. It can be used to sense external pressure by measuring the beat frequency shift of polarization mode. After theoretical derivation and experimental verification, the sensing characteristics of the laser were shown in detail.
