Abstract
Distributed Bragg reflector (DBR) fiber optic laser has recently been extensively explored as a powerful sensor for various measurands, thanks to its high sensitivity, excellent signal-to-noise ratio, and inherent electronic magnetic immunity. The phase noise and linewidth of the laser’s beat note limits this sensor’s performances. We report in this letter, our recent experiments on noise reduction employing optical feedback from an external FBG. We also investigated the sensitivity reduction of the DBR sensor after feedback is introduced.
