  • Optomechanical force sensors, cantilevers, and systems thereof
    Patent number: 10031158
    Abstract: An optomechanical force sensor includes a substrate, a cantilevered beam anchored to the substrate, and a probe tip positioned near an end of the cantilevered beam distal to the substrate. A suspended waveguide is disposed on the cantilevered beam and is optically continuous with an input/output waveguiding structure. An optical cavity is defined within the suspended waveguide.

  • Second harmonic generation in resonant optical structures
    Patent number: 9865987
    Abstract: An optical second-harmonic generator (or spontaneous parametric down-converter) includes a microresonator formed of a nonlinear optical medium. The microresonator supports at least two modes that can be phase matched at different frequencies so that light can be converted between them: A first resonant mode having substantially radial polarization and a second resonant mode having substantially vertical polarization. The first and second modes have the same radial order. The thickness of the nonlinear medium is less than one-half the pump wavelength within the medium.
