Abstract:
A luminescent diode (1) comprises a window layer (4) with sawtooth shaped decoupling steps arranged above an active layer (3). Boundary lines (11) run above the decoupling steps (6) by means of which the current is injected into the active layer (3). The luminescent diode (1) is characterised in having a high decoupling efficiency.
Abstract:
The invention relates to a semiconductor chip with an active thin film layer (2), within which a photon emitting zone (3) is formed and a support substrate (1), for the thin film layer, on an opposing side to the direction of radiation from the chip is connected thereto. At least one cavity (8) is formed in the active thin film layer (2) due to the support substrate (1), by means of which a number of mesa regions (4) are formed at the boundary between support substrate (1) and the thin film layer (2).
Abstract:
The invention relates to a light-emitting diode. The aim of the invention is to improve the coupling out of light. To this end, the light-emitting diode is covered on at least one section of its light exit surface with a plurality of truncated pyramids (10A-D) at the lateral flanks (2A, 2B, 2C) of which the light radiation that is emitted by a light-producing layer and that enters through the base (1) of the truncated pyramids (10A-D) can be efficiently coupled out.

Abstract:
The invention concerns an optoelectronic component (1) for mixing electromagnetic radiation having different wavelengths, more particularly in the far field. At least one first semiconductor chip (3) for emitting electromagnetic radiation in a first spectral range is provided on a carrier (2). Furthermore, at least one second semiconductor chip (4, 4a, 4b) for emitting electromagnetic radiation in a second spectral range is provided on the carrier (2). The first and the second spectral ranges differ from one another. The at least one first semiconductor chip (3) and the at least one second semiconductor chip (4, 4a, 4b) are arranged in a single package. The at least one first semiconductor chip (3) is optically isolated from the at least one second semiconductor chip (4, 4a, 4b) by a barrier (5). The at least one first semiconductor chip (3) and the at least one second semiconductor chip (4, 4a, 4b) are in each case arranged centrosymmetrically about a common centre (Z) of symmetry.
