The acronym DFB laser stands for distributed feedback laser. Their key features relative to other semiconductor lasers are their single longitudinal mode (single frequency) emission profile, their high stability and their wavelength tunability. A DFB laser's periodic structure acts as a distributed reflector, providing optical feedback and. A distributed feedback (DFB) laser is a laser where the optical resonator is formed not by discrete mirrors at the ends (as in Fabry–Pérot laser diodes) but by a periodic variation of the refractive index or gain (a Bragg grating) distributed throughout the active medium.
