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.

Topology optimized multi-layered meta-optics

A fully confined dual frequency optical resonator configured for optical coupling to light having a first frequency &#x3c9;. The dual frequency optical resonator includes a plurality of alternating layer pairs configured in a grating configuration, each layer pair having a first layer formed of a first material and a second layer formed of a second material, the first material and second material being different materials. Each layer having a thickness different than a thickness of an adjacent layer to provide thereby aperiodic layer pairs, the thicknesses of adjacent layers being selected to create, via wave interference with each layer, optical resonances at the first frequency &#x3c9;and a second frequency &#x3c9;which is a harmonic of &#x3c9;, and to ensure a maximum spatial overlap between confined modes over the materials such that an overall quality factor Q of at least 1000 is achieved.
