Patent number: 7135711Abstract: An electroluminescent component (1), in particular an LED chip, which has a high external efficiency in conjunction with a simple construction. The electroluminescent component (1) has a substrate (2); a plurality of radiation decoupling elements arranged at a distance next to one another on the substrate (2) and having an active layer stack (7) with an emission zone (8); and a contact element (9) on each radiation decoupling element (4). The contact elements (9), whose width (b?) is dimensioned such that it is less than the width (b) of the radiation decoupling elements (4), are arranged centrally on the radiation decoupling elements (4), and the width (b) of the radiation decoupling elements (4), for a given height (h), is chosen to be so small that a substantial proportion of the light (11) radiated laterally from the emission zone (8) can be decoupled directly through the side areas (12) of the radiation decoupling elements (4).Type: GrantFiled: August 30, 2002Date of Patent: November 14, 2006Assignee: Osram Opto Semiconductors GmbHInventors: Norbert Linder, Ernst Nirschl, Werner Spath

Publication number: 20050259700Abstract: 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.Type: ApplicationFiled: July 22, 2005Publication date: November 24, 2005Inventors: Werner Spath, Johann Luft, Stephan Lutgen, Norbert Linder, Tony Albrecht, Ulrich Steegmuller
