What is DFB Laser? A Distributed Feedback (DFB) Laser is a single-mode semiconductor laser that uses an internal periodic grating structure to provide optical feedback along the entire gain
Distributed feedback lasers are diode or fiber lasers where the whole laser resonator consists of a periodic structure, in which Bragg reflection occurs.
DML can be categorized into two types as surface emitters like vertical cavity surface emitting laser (VCSEL) [17, 18] and edge emitters including Fabry-Perot (FP) laser [19, 20],
