Optical Flash switching via Electrically Controlled Metasurfaces

Abstract

Recent advancements in nanofabrications, characterisations and computer modellings allow generating of novel metasurfaces that control the light characteristics in extraordinary ways. Such advances have led to revolutionary applications in several fields, including but not limited to metalenses, polarisation converters, nano-sensors, and holograms [1]. Meanwhile, the active and reversible tunning of metasurfaces has attracted significant attention due to the larger degree of freedom that tunable metasurfaces can offer. Tunning metasurfaces can be obtained by various external stimuli, such as mechanical, electrical, optical, etc. [1]. Show more
