ABSTRACT:
An optical semiconductor device used for optical information processing, such as writing information into and reading information from an optical disk. The optical semiconductor device includes a Si substrate, a light emitting element, and a reflector for reflecting light emitted from the light emitting element in a direction perpendicular to the mounting surface of the Si substrate. The reflector has a reflecting surface inclined by 45.degree. from a bottom face and formed by etching a single crystal of Si.
