  • Quantum key distribution with single detector and interferometer based optical switch
    Patent number: 11936779
    Abstract: A method and an apparatus for receiving quantum optical communication while reducing receiver, increasing maximum detection speed, or both. The disclosure comprises transforming the polarization encoded output of a QKD system to time-bin encoded output at the detector level. The disclosure also comprises a method and an apparatus using a quantum optical switch and several SPD units to increase communication speed.

  • See-through display for an augmented reality system
    Patent number: 11927755
    Abstract: An optical system for a see-through display includes a stack of metasurface layers configured to receive light constituting an image; and a waveguide coupled to the stack. Each layer in the stack of metasurface layers is configured to provide a resonant response to an optical field at a different spectral band and to couple the resonant response with a waveguide. The waveguide is configured to propagate the different spectral bands in a direction of a user's eye.

  • System and method for controlling light by an array of optical resonators
    Patent number: 11880047
    Abstract: An array of optical resonators includes at least a first type of optical resonators each having a resonant response to an optical field at a first wavelength, and a second type of optical resonators each having a resonant response to an optical field at a second wavelength, being different from the first wavelength. The resonant responses can be selected to reduce chromatic aberrations, or to shape a profile of a light beam, or to selectively switch a near field beam.
