Abstract:
1. A semiconductor optical device mounting structure, comprising: a semiconductor laser device and a mounting plate on which a second electrode is formed, wherein said semiconductor laser device comprises an active layer, a clad layer formed over said active layer, a surface dielectric film formed over said active layer, a first electrode which is formed over said clad layer and is elongated toward a peripheral region of said semiconductor laser device, and an electrode protection dielectric film which is formed over said surface dielectric film and said clad layer, wherein said surface dielectric film is removed at a top surface of an active region of said semiconductor laser device, wherein said electrode protection dielectric film is selectively removed so that an area above the active region remains coated, and wherein said semiconductor laser device is mounted on said mounting plate in junction down form by mounting said first electrode of said semiconductor laser device on the second electrode of said mounting plate by using solder metal.
