A DFB laser, or distributed feedback laser, is a semiconductor device that emits highly stable, single-frequency light using a built-in grating structure for optical feedback.
Distributed feedback laser (DFB) is widely used as a light source for metro, long-haul, and undersea applications, due to its narrow spectral width, and wavelength stability.
DFB lasers tend to be much more stable than Fabry–Perot or DBR lasers and are used frequently when clean single-mode operation is needed, especially in high-speed fiber-optic telecommunications.
