Kenneth Purchase 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).

  • Method and apparatus facilitating mechanical beam steering for optical integrated circuits
    Patent number: 7539364
    Abstract: Actuators facilitating mechanical beam steering for optical integrated circuits are disclosed. The mechanical beam steering can mitigate thermal sensitivity of optical circuits, for example, arrayed waveguides. Also disclosed are methods for fabricating optical integrated circuits employing actuators.
    Type: Grant
    Filed: September 1, 2005
    Date of Patent: May 26, 2009
    Assignee: NeoPhotonics Corporation
    Inventors: Robert Cole, Michael Guerrero, Kenneth Purchase, Anthony J. Ticknor, Kenneth McGreer, David Menche
  • Athermal AWG and AWG with low power consumption using groove of changeable width
    Patent number: 7062127
    Abstract: Optical integrated circuits are disclosed having a gap traversing the lens or the waveguide grating and an actuator that controllably positions the optical integrated circuit on each side of the gap. As a result, the thermal sensitivity of the optical integrated circuits, for example, arrayed waveguide gratings, is mitigated. Also disclosed are methods for fabricating optical integrated circuits employing the gap and actuator.
