Distributed Feedback Laser
The simple design of fibre lasers with reflectors spread in space along light propagation direction is represented by the so-called distributed feedback (DFB) and distributed Bragg reflector (DBR) lasers.
Distributed Feedback Lasers – DFB laser
What is a distributed feedback (DFB) laser? A DFB laser is a type of laser where the optical feedback is provided by a periodic structure, such as a Bragg grating, that is integrated along the entire length of
