    Abstract: A surface-emitting semiconductor laser device is provided that includes an edge-emitting laser integrated in a semiconductor material with various reflectors and a diffractive lens. The edge-emitting laser has a first section comprising an active MQW region, a second section comprising a passive region and a third section comprising a semi-insulating or un-doped semiconductor bulk layer. This configuration ensures that the injection current will pass through all of the layers of the active region, thereby preventing the occurrence of optical losses due to un-injected areas of the MQW active region. In addition, the inclusion of the passive region ensures that there is no current passing through the interface between the active MQW region and the regrown semiconductor bulk layer. The latter feature improves performance and device reliability.

    Abstract: A surface-emitting semiconductor laser device is provided that includes an edge-emitting laser formed in various layers of semiconductor material disposed on a semiconductor substrate, a polymer material disposed on the substrate laterally adjacent the layers in which the edge-emitting laser is formed, a diffractive or refractive lens formed in or on an upper surface of the polymer material, a side reflector formed on an angled side reflector facet of the polymer material generally facing an exit end facet of the laser, and a lower reflector disposed on the substrate beneath the polymer material. Laser light passes out of the exit end facet and propagates through the polymer material before being reflected by the side reflector toward the lower reflector. The laser light is then re-reflected by the lower reflector towards the lens, which directs the laser light out the device in a direction that is generally normal to the upper surface of the substrate.
