  • Detecting light in whispering-gallery-mode resonators
    Patent number: 8124927
    Abstract: An optical device including a whispering gallery mode (WGM) optical resonator configured to support one or more whispering gallery modes; and a photodetector optically coupled to an exterior surface of the optical resonator to receive evanescent light from the optical resonator to detect light inside the optical resonator.
    Type: Grant
    Filed: May 29, 2007
    Date of Patent: February 28, 2012
    Assignee: California Institute of Technology
    Inventors: Anatoliy Savchenkov, Lutfollah Maleki, Makan Mohageg, Thanh M. Le
  • Optical sensing based on overlapping optical modes in optical resonator sensors and interferometric sensors
    Patent number: 8111402
    Abstract: Techniques and devices based on transverse magnetic (TM) and transverse electric (TE) modes in an optical resonator or interferometer to provide sensitive optical detection with insensitivity to a change in temperature. A shift in a difference between a first resonance wavelength of a TE optical mode and a second resonance wavelength of a TM optical mode is measured to measure a change in a sample that is in optical interaction with the optical resonator or interferometer. For example, the detected shift can be used to measure a change in a refractive index of the sample.
