Abstract
A thin-film optical device disclosed herein includes a metalens able to modulate the phase of incident light. The metalens includes a thin-film layer having a first index of refraction, an embedded layer within the thin-film layer, and the embedded layer having a second index of refraction greater than or equal to 1.5 and less than or equal to 3.0 times the first index of refraction. The embedded layer may fill a plurality of holes formed on the thin film layer, with the depth, width, and spacing of holes all contribute to modulating the phase of light traveling through the metalens.
