  • Patent number: 7135711
    Abstract: 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).

  • Publication number: 20050259700
    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.

  • Patent number: 6946864
    Abstract: A measuring arrangement for measuring product parameters of a component in the epitaxial layer (28) of a wafer comprises measuring probe (3) on whose contact side (23) a recess (24) is installed, into which an electrolyte can be poured. The electrolyte produces an electrical connection between a contact body (11), which is charged with a signal from a pulsed-current source, and the surface (22) of the wafer (2). A detector (16) serves for detecting the light which is emitted by the component.

  • Patent number: 6944199
    Abstract: A semiconductor laser has a semiconductor body with first and second main areas, preferably each provided with a contact area, and also first and second mirror areas. An active layer and a current-carrying layer are formed between the main areas.

  • Patent number: 6806956
    Abstract: A polarization detector is described which contains a beam splitter, which disperses an incident light beam into partial beam paths.
