Patents by Inventor Wayne Wai Wing Lui

Wayne Wai Wing Lui 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 tap for optical integrated circuits
    Patent number: 6928215
    Abstract: Optical circuits are disclosed having a source waveguide, a first tap waveguide and a second tap waveguide. Optical power is transferred via evanescent coupling from the source waveguide to the first tap waveguide and from the first tap waveguide to the second tap waveguide such that power loss is minimized. Also disclosed are methods for fabricating optical integrated circuits.
    Type: Grant

  • Optical mach-zehnder interferometers with low polarization dependence
    Publication number: 20020159702
    Abstract: This relates generally to optical waveguide-based devices including dynamically programmable optical attenuators. In particular, this provides an optical attenuator having a Mach Zehnder configuration with reduced polarization dependence. The devices herein facilitate the implementation of continuously-variable optical attenuators, optical shutters, and optical switches in an integrated photonic circuit.
