英文摘要 | PURPOSE:To enable optical communication extending over a long distance by juxtaposing a plurality of laser light-emitting sections controlled in a transverse mode on the same surface, optically coupling each laser light-emitting section in a Bragg reflection region having periodicity and obtaining a longitudinal single mode enabling operation at a high output. CONSTITUTION:A semiconductor laser device is constituted by a laser light- emitting section 1 consisting of laser light-emitting sections 1a-1e controlled in a transverse mode and a diffraction grating section 2. Several laser light-emitting section 1a-1e is formed in such a manner that a diffraction grating 31 is prepared on an N type crystal 3, a guide layer 4 is formed, the guide layer 4 is removed selectively through etching by an etching liquid, and an active layer 5, an anti-meltback layer 6, a clad layer 7 and a P type surface layer 8 are grown in succession through an epitaxial method. A P type layer 71, an N type layer 72 and a surface layer 73 are shaped as a laser crystal, and a P type electrode 9 and an N type electrode 10 are evaporated and shaped on both surfaces. |
