  • ULTRA-COMPACT, ABERRATION CORRECTED, VISIBLE CHIRAL SPECTROMETER WITH META-LENSES
    Publication number: 20210132272
    Abstract: An optical device includes: (1) a substrate; and (2) multiple meta-lenses disposed on the substrate, each meta-lens of the meta-lenses including multiple nanofins disposed on a respective region of the substrate, the nanofins together specifying a phase profile of the meta-lens.
    Type: Application
    Filed: December 19, 2017
    Publication date: May 6, 2021
    Applicant: PRESIDENT AND FELLOWS OF HARVARD COLLEGE
    Inventors: Alexander Yutong ZHU, Wei Ting CHEN, Mohammadreza KHORASANINEJAD, Jaewon OH, Aun ZAIDI, Robert Charles DEVLIN, Federico CAPASSO
  • HIGH PERFORMANCE VISIBLE WAVELENGTH META-AXICONS FOR GENERATING BESSEL BEAMS
    Publication number: 20190235139
    Abstract: An optical device comprises a substrate and a metasurface. The metasurface comprises a plurality of nanoscale elements disposed on the transparent substrate at different orientations. The orientations of the nanoscale elements define a phase profile such that the nanoscale elements convert an incident light into an output light propagating substantially without diffraction.

  • META-LENSES FOR SUB-WAVELENGTH RESOLUTION IMAGING
    Publication number: 20190154877
    Abstract: A meta-lens having a phase profile includes a substrate and a plurality of nanostructures disposed on the substrate. Each individual nanostructure of the nanostructures imparts a light phase shift that varies depending on a location of the individual nanostructure on the substrate. The light phase shifts of the nanostructures define the phase profile of the meta-lens. The varying light phase shifts can be realized by, e.g., changing orientations of nanofins or changing diameters of nanopillars.

  • CHARGE ORDERED VERTICAL TRANSISTORS
    Publication number: 20160155941
    Abstract: A vertical charge ordered transistor is disclosed. A thin charge ordered layer is employed as a tunnel barrier between two electrodes. A gate-induced accumulation of charge destabilizes the charge ordered state around the circumference of the device, opening up a parallel ohmic conduction channel, which leads to an exponential increase in source-drain current. VCOT devices have the potential to exhibit very large on/off ratios, low off-state currents, and sub-threshold slopes below 60 mV/dec.
