ABSTRACT:
A semiconductor device with a distributed Bragg reflector is disclosed, in which periodic corrugations are formed between two semiconductor layers along the direction of travel of light. In accordance with the present invention, the periodic corrugations are formed by grid-like layers of a refractory material. The refractory material is an insulator, a refractory metal or a laminate member of an insulator and a refractory metal.
