Abstract: An optical device includes a substrate, a single-layer metasurface disposed on the substrate, and a refractive lens. The metasurface and the refractive lens may be configured to bring at least five distinct wavelengths to focus on a same plane.

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.

Abstract: An optical device for aberration correction (e.g., chromatic aberration correction) is disclosed. The optical device includes an optical component (e.g., a spherical lens) and a metasurface optically coupled to the optical component. The metasurface includes a plurality of nanostructures that define a phase profile. The phase profile corrects an aberration (e.g., chromatic aberration) caused by the optical component. The resulting optical device becomes diffraction-limited (e.g., for the visible spectrum) with the metasurface.
