Paper Abstract

We demonstrated a method to trim the beat frequency of dual-polarization fiber grating lasers by exposing the laser cavity to uniform UV beam. The UV-side-illumination induces an additional birefringence of the cavity fiber and therefore permanently changes the beat frequency of the laser. The beat frequency can be trimmed to longer or shorter frequency range in a large frequency range. A 6-channel RF-frequency division multiplexed polarimetric fiber grating laser sensor array was demonstrated.
