WebA 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. WebDownload from our library of free Light sound effects.
