  • Meta-lenses for sub-wavelength resolution imaging
    Patent number: 11092717
    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.
    Type: Grant
    Filed: April 5, 2017
    Date of Patent: August 17, 2021
    Assignee: PRESIDENT AND FELLOWS OF HARVARD COLLEGE
    Inventors: Federico Capasso, Wei-Ting Chen, Robert C. Devlin, Mohammadreza Khorasaninejad, Jaewon Oh, Alexander Yutong Zhu, Charles Roques-Carmes, Ishan Mishra
