摘要： 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.
