Automated Design of Optical Systems with Metalenses

Abstract

Recent advances in metalens technology have created a demand for robust and efficient computer-aided design. Here we showcase the automated design of metalens systems by demonstrating both chiral holograms and a large FOV achromatic doublet.

Fully automated inverse design solution for metalenses/metasurfaces

“…If the phase difference is maintained at 180 o , incident light with right-hand circular polarization (RCP) can turn into left-hand circular polarization (LCP), and vice versa. With a proper geometric phase profile over the metasurface, achieved by rotating the fin of each meta-atom, a metalens can display different images for incident light with different circular polarizations [14].…”

“…To determine the right geometric phase profile for such an application, extensive design knowledge and effort are typically required. With MOD, this complex design becomes more accessible to non-experts and even undergraduate students [14].…”
