ABSTRACT:
A two dimensional, surface-emitting array of semiconductor lasers. Lasers disposed on a semiconductor substrate emit light in a direction substantially parallel to the substrate surface into a high index material in which the lasers are embedded. Internal reflectors composed of a low index material, also embedded in the high index material, reflect the laser beams to the surface of the array. The indexes of the low index material and the high index material are chosen so that none of the light enters the internal reflector, and all light is reflected to the laser array surface.
