Abstract:
Multi-wavelength light is directed to an optic including a substrate and metasurface optical components deposited on a surface of the substrate. The metasurface optical components comprise a pattern of silicon dielectric resonators with nonperiodic gap distances between adjacent dielectric resonators. Incident light directed to the metasurface optical components is scattered and phase-shifted by the configuration of the gap distances and the widths and thicknesses of the dielectric resonators. Each dielectric resonator has a rectangular cross-section 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.
