Patent number: 8115226Abstract: An electrode structure is disclosed for enhancing the brightness and/or efficiency of an LED. The electrode structure can have a metal electrode and an dielectric material formed intermediate the electrode and a light emitting semiconductor material. Electrical continuity between the semiconductor material and the metal electrode is provided by an optically transmissive ohmic contact layer, such as a layer of Indium Tin Oxide. The metal electrode thus can be physically separated from the semiconductor material by one or more of the dielectric material and the ohmic contact layer. The dielectric layer can increase total internal reflection of light at the interface between the semiconductor and the dielectric layer, which can reduce absorption of light by the electrode. Such LED can have enhanced utility and can be suitable for uses such as general illumination.Type: GrantFiled: September 22, 2010Date of Patent: February 14, 2012Assignee: Bridgelux, Inc.Inventors: Frank T.

Patent number: 8114690Abstract: Aspects concerning a method of making electrical contact to a region of semiconductor in which one or more LEDs are formed include that a dielectric region can be formed on a p region of the semiconductor, and that a metallic electrode can be formed on (at least partially on) the region of dielectric material. A transparent layer of a material such as Indium Tin Oxide can be used to make ohmic contact between the semiconductor and the metallic electrode, as the metallic electrode is separated from physical contact with the semiconductor by one or more of the dielectric material and the transparent ohmic contact layer (e.g., ITO layer). The dielectric material can enhance total internal reflection of light and reduce an amount of light that is absorbed by the metallic electrode.Type: GrantFiled: September 22, 2010Date of Patent: February 14, 2012Assignee: Bridgelux, Inc.Inventors: Frank T.

Publication number: 20120033113Abstract: Emissive quantum photonic imagers comprised of a spatial array of digitally addressable multicolor pixels. Each pixel is a vertical stack of multiple semiconductor laser diodes, each of which can generate laser light of a different color. Within each multicolor pixel, the light generated from the stack of diodes is emitted perpendicular to the plane of the imager device via a plurality of vertical waveguides that are coupled to the optical confinement regions of each of the multiple laser diodes comprising the imager device. Each of the laser diodes comprising a single pixel is individually addressable, enabling each pixel to simultaneously emit any combination of the colors associated with the laser diodes at any required on/off duty cycle for each color. Each individual multicolor pixel can simultaneously emit the required colors and brightness values by controlling the on/off duty cycles of their respective laser diodes.Type: ApplicationFiled: October 21, 2011Publication date: February 9, 2012Applicant: OSTENDO TECHNOLOGIES, INC.Inventors: Hussein S.
