Paper Abstract

A high sensitivity displacement sensor based on a dual-polarization fiber grating laser incorporated with a cantilever beam is demonstrated. The cantilever beam transforms the displacement into a transverse force to the fiber grating laser which changes the fiber birefringence and therefore the polarization mode beat frequency of the laser. A sensitivity of 0.535 GHz/mm is implemented.
