Abstract

Metalens is optical components that can replace traditional multi-element lens designs, offering the advantages of aberration elimination, high numerical aperture, and wide field-of-view imaging capabilities. However, engineering nano-antennas within metalens, especially in wide-angle configurations at the millimeter scale, presents challenges. These nanostructures must effectively control phase and amplitude to meet the required phase for different angles of incidence, while also achieving focal spot sizes close to the diffraction limit. This study utilizes the Synopsys simulation tool, "MetaOptic Designer," to design and optimize a metalens with a 1mm diameter and a numerical aperture (NA) of 0.37, operating at a 940 nm wavelength.
