  • Patent number: 11537025
    Abstract: Embodiments relate to a photonic component having a metasurface. The metasurface includes a substrate with a thin-layer of meta-atoms disposed thereon. The photonic component includes a waveguide having a top surface, wherein the metasurface is disposed on at least a portion of the top surface such that the meta-atoms form an array on the top surface. The photonic component includes a sandwich nano-bar antenna formed in or on the metasurface.
    Type: Grant

  • Patent number: 10883799
    Abstract: This disclosure provides systems, methods, and devices related to a metasurface skin cloak. In one aspect, a metasurface skin cloak includes a dielectric layer and a plurality of blocks disposed on the dielectric layer. The dielectric layer is disposed over a surface including a feature on the surface. Each block of the plurality of blocks has a shape that is symmetric about two perpendicular axes. The metasurface skin can render the feature on the surface not optically detectable.

  • Patent number: 10690817
    Abstract: An ultra-thin planar device is used for arbitrary waveform formation on a micrometer scale, regardless of the incident light's polarization. Patterned perforations are made in a 30 nm-thick metal film, creating discrete phase shifts and forming a desired wavefront of cross-polarized, scattered light. The signal-to-noise ratio of these devices is at least one order of magnitude higher than current metallic nano-antenna designs. The focal length of a lens built on such principle can also be adjusted by changing the wavelength of the incident light. All proposed embodiments can be embedded, for example, on a chip or at the end of an optical fiber.

  • Publication number: 20190041260
    Abstract: According to some embodiments of the invention, an electro-optic device includes a first plurality of electrodes, a second plurality of electrodes spaced apart from the first plurality of electrodes, and an active layer between the first plurality of electrodes and the second plurality of electrodes. The active layer comprises a plurality of electromagnetic resonators. At least one of the first plurality of electrodes and the second plurality of electrodes is at least partially transparent to light of a spectral range that can be absorbed or emitted by the plurality of electromagnetic resonators. The first and second plurality of electrodes are electrically connected to the plurality of electromagnetic resonators. The spacings between at least a selected pair of the plurality of electromagnetic resonators is provided such that a real component of a coupling coefficient between the selected pair of the plurality of electromagnetic resonators is substantially canceled.
