A distributed-feedback laser (DFB) is a type of laser diode, quantum-cascade laser or optical-fiber laser where the active region of the device contains a periodically structured element or diffraction grating. The structure builds a one-dimensional interference grating (Bragg scattering), and the grating provides optical feedback for the laser. This longitudinal diffraction grating has periodic changes in refractive index that cause reflection back into the cavity. The periodic change can b… WebApr 26, 2024 · It is generally known that single longitudinal mode (SLM) distributed feedback (DFB) lasers have become widely used devices due to their mature production process, small volume and low cost 1 ...
