    Abstract: The invention relates to a semiconductor laser device comprising an optically pumped surface-emitting vertical emitter (1) which emits in a vertical main radiating direction, and at least one monolithically integrated pumping radiation source (2) for optically pumping the vertical emitter (1), the pumping radiation source emitting pumping radiation that extends transversal to the vertical main radiating direction. According to a first embodiment, the inventive semiconductor laser device is characterized in that at least one vertical section of the pumping radiation source (2) is configured so as to be index-guiding for pumping radiation in a lateral direction perpendicular to the main direction of pumping radiation and perpendicular to the vertical main radiating direction. In a second embodiment, the semiconductor laser device is characterized in that the pumping radiation source (2) has a smaller width in a lateral direction perpendicular to the main direction of pumping radiation in at least one vertical section than in another vertical section. If the dimensions are adequate, modes of the pumping radiation can thus be entirely or at least partly displaced from said section in a vertical direction, resulting in a reduction of absorption losses of the pumping radiation on conducting layers.

    Abstract: The invention relates to a thin-film light-emitting diode chip in which the distance between a reflective layer (4) and a light-generating active zone (3) is such that radiation from the active zone (3) interferes with light reflected by the reflective layer (4). The interference affects the internal quantum efficiency of the active zone (3), and consequently the active zone has an emission characteristic with at least one preferred direction.

    Abstract: The invention relates to a semiconductor device comprising an optically pumped vertical emitter that is provided with an active vertical emitter layer (3) and a pumping radiation source by means of which a pumping radiation field is generated that propagates in a lateral direction while optically pumping the vertical emitter layer (3) in a pumping zone, the wavelength of the pumping radiation field being smaller than the wavelength of the radiation field (12) generated by the vertical emitter. The pumping radiation source encompasses an active pumping layer (2) that is disposed downstream of the vertical emitter layer (3) in a vertical direction and at least partly overlaps with the vertical emitter layer from a vertical perspective. The active pumping layer (2) is arranged in such a way that the pumping radiation field generated during operation is more powerful than a parasitic, laterally propagating radiation field generated by the vertical emitter layer (3). Alternatively, a parasitic, laterally propagating radiation field is prevented from being generated by the vertical emitter layer (3).
