MULTI-BEAM TYPE SEMICONDUCTOR OPTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor optical device where two or more semiconductor light-emitting elements of different light-emission wavelength and integrated on a single substrate and which is manufactured with high yield and yield. SOLUTION: Two or more stripe-like channels are provided on a semiconductor substrate or an epitaxial growth layer grown on it, with active layers of different light-emission wavelength being formed in at least two channels.
