Digital OPLL-based distributed Brillouin sensing system in optical fibers

Chin, Sanghoon; Denis, Séverine; Kundermann, Stefan; Brasch, Victor; Lecomte, Steve (2022-05-23)

A digital optical phase-locked loop (OPLL) has been implemented to develop a distributed Brillouin sensing system in optical fibers. In our experiment, two commercial semiconductor lasers are phase-locked to each other ...
