08/13/21 "Polarization-Insensitive Medium-Switchable Holographic Metasurfaces" in ACS Photonics

Our paper "Polarization-Insensitive Medium-Switchable Holographic Metasurfaces" is published in ACS Photonics ( In this work, we demonstrate polarization-insensitive metasurfaces encoding independent holograms, which can be switched by changing the infiltration medium while maintaining identical illumination conditions. By sidestepping the requirements for high-performance light sources, switching optics, or delicate alignment, this approach points toward ultracompact and cost-effective switchable meta-holograms for various practical applications, such as holographic image projection, eye-perceptible sensors, optical information storage, processing, and security.
