Patents by Inventor Gary Duck

Gary Duck 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).

  • Apparatus and method for generation of optical signals
    Patent number: 6552782
    Abstract: A laser system is disclosed wherein a tunable laser signal has encoded within it information related to its wavelength at any instant in time. This encoding in one example is performed by modulating the signal to contain its wavelength information. This is particularly useful in a distributed system for testing optical components, wherein at a test site, the test station must determine the wavelength of light at which a component was tested.
    Type: Grant
    Filed: February 25, 2002
    Date of Patent: April 22, 2003
    Assignee: JDS Uniphase Corporation
    Inventors: Paul Colbourne, Gary Duck, Bruce Nyman, Donald R. Zimmerman
  • Coupling of light into a monolithic waveguide device
    Patent number: 6438291
    Abstract: An optical system for coupling light from a monolithic waveguide chip from one optical path to another on different layers of the chip or into or out of the chip along an edge thereof by coupling a GRIN lens to the edge. Coupling a GRIN lens having a reflective end allows light to be launched out of and back into the waveguide chip. Alternatively a GRIN lens having a plurality of fibers coupled thereto can be used to couple signals carried by the fibers into the waveguide chip.
