Abstract: A subassembly for coupling a laser to an optical fiber (19) comprises a substrate (10) having an asymmetrical, pyramidal cavity (13), a spherical lens (15) located in the cavity, and a semiconductor laser (17) positioned on the substrate. The output face of the laser is located along an edge (14) of the cavity (without overhanging the edge), and its active region (17.1) is aligned with the center (15.1) of the lens along the optic axis (16) of the subassembly.

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.
