LASERS WITH BEAM SHAPE AND BEAM DIRECTION MODIFICATION

摘要

A reflective surface is disclosed in conjunction with a semiconductor laser to shape a laser beam and modify a direction of the laser beam. The reflective surface may be formed on a structure disposed adjacent to a laser structure to allow high coupling of laser light to, for example, a silicon photonics chip or an optical fiber.

主权项

1. A semiconductor laser, comprising:
a substrate; a laser structure on the substrate, the laser structure comprising an active region that emits light; an etched facet formed in the laser structure that exposes at least a portion of the active region; and a reflective surface disposed adjacent the etched facet to receive and reflect light emitted from the active region, the reflective surface having a curvature.
