Abstract

A multi-layered lens comprises a plurality of metasurface layers. At least some layers of the plurality of metasurface layers include features that exhibit angular phase controls. The angular phases of the at least some layers cause an angular aberration correction or an angle convergence that focuses light onto a focal point regardless of angles of incidence.
