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