Timothy A. Handley 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 filter having coupled whispering-gallery-mode resonators
    Patent number: 6987914
    Abstract: Optical filters having at least two coupled whispering-gallery-mode (WGM) optical resonators to produce a second order or higher order filter function with a desired spectral profile. At least one of the coupled WGM optical resonators may be tunable by a control signal to adjust the filtering function.
    Type: Grant
    Filed: November 4, 2003
    Date of Patent: January 17, 2006
    Assignee: California Institute of Technology
    Inventors: Anatoliy Savchenkov, Vladimir Ilchenko, Lutfollah Maleki, Timothy A. Handley
  • Whispering gallery mode resonators based on radiation-sensitive materials
    Patent number: 6922497
    Abstract: Whispering gallery mode (WGM) optical resonators formed of radiation-sensitive materials to allow for permanent tuning of their resonance frequencies in a controlled manner. Two WGM resonators may be cascaded to form a composite filter to produce a second order filter function where at least one WGM resonator is formed a radiation-sensitive material to allow for proper control in the overlap of the two filter functions.
