摘要

Optical metasurface is a recently emerged paradigmfor controlling light propagation, which enables implementationof ultra-compact optical devices with extended functionalities.Nowadays the main challenge in the field is to realize activemetasurfaces with high quality, high efficiency, and large tuningrange. Here we present a design approach for constructing a twostatereconfigurable metalens made of low-loss optical phasechangematerial (O-PCM). The metalens design is capable toproduce diffraction limited focusing, large change in focal length(from 1.5 mm to 2mm), and decent focusing efficiency of about20% in both states. The proposed design methodology is genericand can be easily extended towards constructing metasurfaces,which can switch between two or more arbitrary phase maps.
