ABSTRACT:
There is disclosed, an optical subassembly includes a platform on which a laser and photodiode are mounted. The laser has a rear facet through which passes a small portion of the light emitted by the laser. The photodiode is mounted on the surface of the platform with a light admitting facet for receiving a portion of the light emitted from the rear facet of the laser being substantially perpendicular to the light emitting facet of the laser. The surface of the platform may include a channel. The channel may be tapered from a narrower end near the laser to a wider end near the photodiode, and may be coated with a light-reflective material.
