ABSTRACT:
A semiconductor injection laser is mounted on a silicon substrate. An optical detector is integral to the substrate and aligned at oblique angles relative to the path of the light from one of the light emitting facets of the laser. The detector may be connected to the current control circuit for the laser to provide a feedback signal which is proportional to the light deflected from the facet. The transversely disposed detector may also function to detect light from another source as part of an optical communication system. The detector may be a Schottky barrier or a p-n junction.
