Abstract: There is disclosed, an optical subassembly (10) includes a platform (12) on which a laser (18) and photodiode (14) are mounted. The laser (18) has a rear facet (42) through which passes a small portion of the light emitted by the laser (18). The photodiode (14) is mounted on the surface of the platform with a light admitting facet (44) for receiving a portion of the light emitted from the rear facet (42) of the laser being substantially perpendicular to the light emitting facet (42) of the laser. The surface of the platform may include a channel (34). The channel (34) may be tapered from a narrower end (36) near the laser (18) to a wider end (38) near the photodiode (14), and may be coated with a light-reflective material.
