  • Patent number: 11137617
    Abstract: An array of optical resonators comprises 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.
    Type: Grant

  • Publication number: 20210181515
    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.
