Patents by Inventor Katherine C.f. Phillips

Katherine C.f. Phillips 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).

  • All-optical logic gates and methods for their fabrication
    Patent number: 8989544
    Abstract: The present invention provides optical devices that employ nonlinear optical effects for processing optical signals. For example, such an optical device can include a nano-sized interferometric component that provides an optical output signal via interference of two input signals subsequent to their asymmetric nonlinear phase accumulation. The interferometric element can have a variety of configurations, such as Sagnac, Mach-Zehnder or Michelson configurations.
    Type: Grant
    Filed: January 8, 2010
    Date of Patent: March 24, 2015
    Assignee: President & Fellows of Harvard College
    Inventors: Eric Mazur, Rafael R. Gattass, Geoffry T. Svacha, Katherine C. F. Phillips, Christopher C. Evans
