  • Optoelectronic semiconductor component and photonic crystal
    Patent number: 8963120
    Abstract: An optoelectronic semiconductor component includes a semiconductor layer sequence having at least one active layer, and a photonic crystal that couples radiation having a peak wavelength out of or into the semiconductor layer sequence, wherein the photonic crystal is at a distance from the active layer and formed by superimposition of at least two lattices having mutually different reciprocal lattice constants normalized to the peak wavelength.
    Type: Grant
    Filed: November 2, 2010
    Date of Patent: February 24, 2015
    Assignees: OSRAM Opto Semiconductors GmbH, The University Court of the University of St. Andrews
    Inventors: Krister Bergenek, Christopher Wiesmann, Thomas F. Krauss
