The principle of Distributed Bragg Reflector (DBR) LDs is the use of alternating layers of materials with different refractive indices to form a Bragg grating, which is used to reflect light of a specific wavelength back into the active region of the laser diode. This leads to increased optical gain and improved performance of the laser diode.
