Abstract

Metasurface holograms that can be dynamically controlled have attracted wide attention and been realized in many ways. In particular, the phase change materials (PCMs) that can be switched into amorphous and crystalline states at high speed by external thermal stimulation are one of the most promising candidates to break the limitations of material properties and fixed structures. Here we propose a metasurface hologram that aims to realize a dual display that can reconstruct different images by annealing thermal stimulation. The designed metasurface incorporates alternated chalcogenide PCMs cubes and sector columns that possess uniform amplitude and full ${2}\pi $ phase coverage. Simplicity and compactness make this metadevice able to be easily integrated into various applications such as memory storage, augmented reality, anti-counterfeiting, and so on.
