  • Ultra-thin color phase hologram with metasurfaces
    Patent number: 10754295
    Abstract: A device for producing a subwavelength hologram. The device comprises a metasurface layer attached to a substrate. The metasurface layer includes an array of plasmonic antennas that simultaneously encode both wavelength and phase information of light directed through the array to produce a hologram. The wavelength is determined by the size of the antennas, and the phase is determined by the orientation of the antennas.
    Type: Grant

    Date of Patent: August 25, 2020
    Assignee: Purdue Research Foundation
    Inventors: Amr Shaltout, Sajid Choudhury, Alexander V. Kildishev, Alexandra Boltasseva, Vladimir M. Shalaev
  • SENSOR FOR HYPERSPECTRAL IMAGING BASED ON A METASURFACE-INTEGRATED LIGHT DETECTOR ARRAY
    Publication number: 20200025610
    Abstract: A spectroscopic microscope device, comprising at least one array of metasurfaces, and at least one CCD array integrated with the array of metasurfaces. The metasurfaces in the array are configured to separately direct LCP an RCP components of light incident on the metasurface to separate pixels in the CCD array.

  • SUB-MILLIMETER REAL-TIME CIRCULAR DICHROISM SPECTROMETER WITH METASURFACES
    Publication number: 20190219447
    Abstract: A circular dichroism spectrometer which comprises a metasurface. The metasurface has a plurality of anisotropic antennas configured to simultaneously spatially separate LCP and RCP spectral components from an incoming light beam. An optical detector array is included which detects the LCP and RCP spectral components. A transparent medium is situated between the metasurface and the optical detector array.

  • TIME-VARYING METASURFACE STRUCTURE
    Publication number: 20170235162
    Abstract: A time-varying optical metasurface, comprising a plurality of modulated nano-antennas configured to vary dynamically over time. The metasurface may be implemented as part of an optical isolator, wherein the time-varying metasurface provides uni-directional light flow. The metasurface allows the breakage of Lorentz reciprocity in time-reversal. The metasurface may operate in a transmission mode or a reflection mode.
