Patent number: 5171707Abstract: A method of fabricating a semiconductor laser device includes disposing a lower cladding layer, a superlattice active layer, an upper cladding layer, and a contact layer in the named order on a substrate, forming resonator end surfaces, disposing, on the resonator end surfaces, films containing a material that disorders the semiconductor superlattice structure when diffused into the superlattice structure, and passing a current between the substrate and the contact layer to cause laser oscillations. The laser oscillations produce laser light that is absorbed at the resonator end surfaces. The resonator end surfaces are locally heated due to absorption of laser light whereby the disorder-causing material is diffused from the films into the resonator end surfaces and the semiconductor superlattice structure in the vicinity of the resonator end surfaces is thereby disordered to form window regions.Type: GrantFiled: August 13, 1991Date of Patent: December 15, 1992Assignee: Mitsubishi Denki Kabushiki KaishaInventor: Kazuhisa Takahashi
