Abstract: To reduce the fluctuation of frequency response of a DistributedFeedback (DFB) fiber laser used in underwater sound detection, an encapsulated structure with orifices was designed.
Nowadays, the optical pulse used in the OTDM system is often generated by the gain-switched distributed-feedback (GS-DFB) semiconductor laser, which has a large pulse width and negative chirp.
