ABSTRACT:
An optical semiconductor device module comprising a light emitting element, an optical fiber, a light receiving element and an optical filter. The optical semiconductor module further includes a light absorbing-reflecting section for absorbing some of the stray beams which cannot pass through the optical filter, and reflecting some of such stray beams in a direction opposite to an optical axis of the beams. The light absorbing-reflecting section is present in a module casing such that it faces, on the optical axis, the light receiving element via the optical filter.
