Abstract:
A method for fabricating a semiconductor optical device, comprising the steps of:(a) sequentially forming a semiconductor electrode layer of a first conductive type and a first silicon oxide film on a substrate; (b) patterning a desired region of said first silicon oxide film into a desired shape to partially expose said semiconductor electrode layer of said first conductive type and etching the resultant exposed region of said semiconductor electrode layer of said first conductive type to a desired depth to form a groove; (c) forming a second silicon oxide film on a bottom of said groove; (d) growing a semiconductor layer of said first conductive type from side walls of said groove up to a part of said first silicon oxide film on the periphery of said groove; (e) sequentially growing a cladding layer of said first conductive type, an active layer of said first conductive type, a cladding layer of a second conductive type and a semiconductor electrode layer of said second conductive type on said semiconductor layer of said first conductive type to form an optical cavity mirror; and (f) forming electrodes of said first and second conductive types respectively on said semiconductor electrode layers of said first and second conductive types.
