Gregory Jason Parker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical devices and methods of fabrication thereof
    Patent number: 6901194
    Abstract: An optical device includes a waveguide bounded by a region containing a photonic band gap the properties of which determined the transfer characteristic of the waveguide. Such a device may serve as a component of, for example a wavelength division multiplexer, a monochromatic laser or a chemical sensor. It may serve as an optical bus for an electronic component such as a microprocessor. These devices are particularly suitable for incorporation in optical and opto-electronic intergrated circuits as they permit the fabrication of waveguides having right-angle bends with a radius of the order of 2 ?m.
    Type: Grant
    Filed: February 3, 2004
    Date of Patent: May 31, 2005
    Assignee: BTG International Limited
    Inventors: Martin David Brian Charlton, Gregory Jason Parker
