  • JONES MATRIX HOLOGRAPHY WITH METASURFACES
    Publication number: 20240094439
    Abstract: An optical component can include a substrate. The optical component can include a metasurface disposed on the substrate. The metasurface can include one or more linearly birefringent elements. A spatially-varying Jones matrix and a far-field of the metasurface can define a transfer function of the metasurface configured to generate a controlled response in the far-field according to polarization of light incident on the metasurface.

  • Polarization state generation with a metasurface
    Patent number: 11867937
    Abstract: The present disclosure provides an optical component, which may be a metasurface grating, including (a) a substrate; and (b) an array of subwavelength-spaced phase-shifting elements, which are tessellated on the substrate to produce, when illuminated with a polarized incident light, a diffracted light beam with a distinct polarization state for each of a finite number of diffraction orders, wherein the finite number is 2 or more.

  • ARBITRARY POLARIZATION-SWITCHABLE METASURFACES
    Publication number: 20230288716
    Abstract: An optical component comprises a metasurface comprising nanoscale elements. The metasurface is configured to receive incident light and to generate optical outputs. The geometries and/or orientations of the nanoscale elements provide a first optical output upon receiving a polarized incident light with a first polarization, and provide a second optical output upon receiving a polarized incident light with a second polarization that is different from the first polarization.
