Abstract
Metasurface optical components deposited on the surface of a substrate are used to alter incident light. The metasurface optical components comprise a pattern of silicon dielectric resonators that have nonperiodic gap distances between adjacent silicon dielectric resonators; and each silicon dielectric resonator is an elongated rectangular prism that has a width, a length, and a thickness. Incident light is directed to the metasurface optical components, wherein the gap distances, the widths, and the thicknesses are configured to scatter the incident light and impart a phase shift, ranging at least from 0 to 2π, on an outgoing light. Each dielectric resonator has a rectangular cross-section in a plane perpendicular to the substrate surface such that a first phase shift is imparted for a transverse-electric (TE) component of the incident light and a second phase shift is imparted for a transverse-magnetic (TM) component of the incident light.
