A semiconductor chip is specified, comprising an active layer provided for emitting an electromagnetic radiation, and a two-dimensional arrangement of structural units, which is disposed downstream of the active layer in a main emission direction of the semiconductor chip. The structural units are arranged in an arbitrary statistical distribution. Such an arrangement of structural units makes it possible to realize a semiconductor chip having a directional emission characteristic.

摘要:
A semiconductor device comprising an optically pumped vertical emitter having an active vertical emitter layer (3), and a pump radiation source, which is used to generate a pump radiation field which propagates in the lateral direction and optically pumps the vertical emitter layer (3) in a pump region, the wavelength of the pump radiation field being smaller than the wavelength of the radiation field (12) generated by the vertical emitter. The pump radiation source has an active pump layer (2), which is arranged downstream of the vertical emitter layer (3) in the vertical direction and which at least partly overlaps the vertical emitter layer as seen in the vertical direction, the active pump layer (2) being arranged in such a way that the pump radiation field generated during operation has a higher power than a parasitic laterally propagating radiation field generated by the vertical emitter layer (3) or that the generation of a parasitic laterally propagating radiation field by the vertical emitter layer (3) is suppressed.

摘要:
The invention is directed to an optically pumped surface-emitting semiconductor laser device having at least one radiation-generating quantum well structure and at least one pump radiation source for optically pumping the quantum well structure, whereby the pump radiation source comprises an edge-emitting semiconductor structure. The radiation-generating quantum well structure and the edge-emitting semiconductor structure are epitaxially grown on a common substrate. A very efficient and uniform optical pumping of the radiation-generating quantum well structure is advantageously possible with this monolithically produced semiconductor laser device. Methods for manufacturing inventive semiconductor laser devices are also specified.
