Abstract
An optoelectronic module includes a laser, a ball lens, a substrate, a reflector, and a focusing lens. The laser generates a diverging light beam along an optical axis. The ball lens has a center. The substrate has a surface supporting the laser and an alignment structure. The alignment structure registers the ball lens in a plane parallel to the substrate surface and in a direction normal to the substrate surface so that the center of the ball lens is substantially aligned with the optical axis and the ball lens parallelizes the diverging light beam into a collimated beam. The reflector deflects the collimated beam to produce a deflected collimated beam in a plane intersecting the substrate surface. The focusing lens focuses the deflected collimated beam.
