Optische Halbleitervorrichtung mit verbesserter Positionierung des optischen Strahls

摘要

An optical semiconductor apparatus includes a laser diode (2) for producing an optical beam, a base body (22) formed with a first reference surface (23) adapted for engagement with an external apparatus and a second reference surface (25-2a) separated from the first reference surface with a predetermined distance, and a subcarrier member (21) having a principal surface (21a) for carrying the laser diode thereon said principal surface, wherein the subcarrier is mounted upon the base body in an abutted state such that the principal surface establishes an intimate engagement with the second reference surface. The base body is formed with a depression on the second reference surface so as to accommodate therein the laser diode when the subcarrier member is mounted upon the base body together with the laser diode that is mounted upon the principal surface.
