Abstract

In this paper, a bending sensor based on distributed Bragg reflector (DBR) fiber laser with single longitudinal mode operation is presented and experimentally demonstrated. The single longitudinal mode has two split orthogonal polarization modes, introducing the intracavity birefringence and hence causing the emergence of frequency beat. Based on the bending induced birefringence, this laser can be used for curvature sensing by measurement of the beat frequency shift of polarization mode. The sensing characteristics of the laser were shown in detail through theoretical analysis and experimental verification.
