Abstract: An injection laser comprises a laser heterostructure, at least one radiation inflow region adjoining the laser heterostructure, and reflectors that together form an optical resonator. The laser heterostructure comprises an active layer, cladding layers, and ohmic contacts. The radiation inflow region adjoining the laser heterostructure is transparent to the laser radiation and is located on at least one side of the active layer. The radiation inflow region additionally includes at least one optical facet, an outer surface, and an inner surface. Radiation generated in the active layer flows into the radiation inflow region and exits the laser.

Abstract: An injection incoherent Emitter outputs a directed beam of light resulting from spontaneous emission. The Emitter provides small divergence angles and enhanced external efficiency, as well as increased energy and light power. Specific ranges of compositions and thicknesses for layers and sublayers in the entire heterostructure, as well as for the layers of the emission output area may be employed to create this Emitter. Different embodiments for the heterostructure and output areas permit emission from the Emitters in different but controllable directions. One such direction is perpendicular to the active layer. Other embodiments include multibeam incoherent Emitters, including embodiments that emit from lines and arrays of Emitters, wherein each Emitter has an independently controllable beam.
