Abstract: In an optically pumpable surface-emitting semiconductor laser device with a vertical emitter with a radiation-generating active layer, at least one modulation radiation source for modulating the output power of the surface-emitting semiconductor device is provided. The modulation radiation source is formed by an edge-emitting semiconductor structure with an active layer, and which is disposed such that during operation it radiates into the radiation-generating active layer of the vertical emitter. This produces an easily modulatable surface-emitting laser source of high power and high beam quality. A pumping radiation source for optically pumping the active layer of the vertical emitter is preferably provided in the semiconductor laser device.

Abstract: An optoelectronic component has a carrier body as well as an optoelectronic transmitter for emitting a coherent light beam and an optoelectronic receiver, which are applied on the carrier body. An optical device splits the light beam emitted by the optoelectronic transmitter into a reference beam and a measurement beam. The measurement beam reflected at the measurement object is received and superposed with the reference beam to form an interference beam. The interference beam is directed onto the optoelectronic receiver. The optoelectronic component furthermore contains a spacer, which is applied on the carrier body and on which the optical device is applied. The optical device is disposed parallel to and at a distance from the carrier body defined by the spacer.

Abstract: The present invention relates to an optical encoder for measuring the speed and direction of a moving raster. The raster may be moving linearly or angularly and may further be connected to a moving element, such as a spinning shaft, of which speed and orientation measurement Is sought. The raster may comprise a slit plate or the like and include many formations in sequence. The formations may be successively opaque and transparent to light. The raster modulates light from a light source and the modulated light is detected by at least one set of three photodetectors. Output of the photodetectors is then used to generate a reference signal to which individual outputs are compared. The results of the comparisons are indicative of the speed and direction of the raster and moving element to which the raster is attached.
