Claim:
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; a reflective surface disposed apart from the etched facet to receive and reflect light emitted from the active region through a single medium, the reflective surface having a curvature; and a flat patio surface formed on the substrate and disposed between and adjacent to both the etched facet and the reflective surface, the flat patio surface separating the etched facet and the reflective surface directly beneath the active region by a first distance, the flat patio surface forming a plane that runs parallel to a center plane of the active region, the plane of the flat patio surface and the center plane of the active region separated by a second distance, the center plane of the active region and a plane parallel to the center plane of the active region and touching a top of the reflective surface separated by a third distance, wherein the first distance is greater than the second distance and approximately equal to the third distance.
