  • Carbon-based semiconductors
    Patent number: 8866265
    Abstract: All-carbon-based semiconductor devices are provided. In accordance with an example embodiment, an apparatus includes n-type and p-type carbon-based semiconductor material that form a p-n junction, which are respectively coupled to electrodes having a carbon allotrope. A first one of electrodes is connected to the n-type material and a second one of the electrodes is connected to the p-type material, and collect charge presented at the p-n junction.

  • Light coupling device and system, and method for manufacturing the device and system
    Patent number: 8503073
    Abstract: Embodiments of the disclosed technique disclose an optical device generating light by luminescence comprising a substrate, a waveguide, a pump light source and a photoluminescent layer, wherein the waveguide is positioned between the substrate and the photoluminescent layer, or the photoluminescent layer is positioned between the substrate and the waveguide. The pump light source is provided opposite to the photoluminescent layer at the backside of the substrate. The pump light source is adapted to pump the photoluminescent layer to emit light; and at least some of the emitted light is evanescently coupled into the waveguide.
