Abstract
An optical receiver of a bidirectional optical communication module is fabricated through an assembling process in which multiple modules are assembled concurrently. The module includes a first substrate formed with a groove, an optical fiber located in the groove and having a flat surface, a reflective filter inserted between the first substrate and the fiber with a predetermined inclination angle in order to reflect an incident optical signal, a second substrate supporting the fiber and mounted on the first substrate such that the flat surface.
Claims20
An optical receiver of a bidirectional optical communication module, the optical receiver comprising:
