Abstract

Here, we developed two types of tunable PVA metaphotonic platforms, which are 1) PVA metasurface that simultaneously displays a far-field holographic image and reflective structural coloration under coherent and incoherent light, respectively, and 2) humidity-responsive structural coloration that enables to generate RGB color in a single pixel. Three types of PVA metasurfaces have been designed: 1) revisable holography/structural coloration with pure PVA structures, 2) relative-humidity sensitive optical decryption with PVA-hydrogenated amorphous silicon structures, and 3) revisable holography/structural coloration with Pt-coated PVA structures. Considering that the aforementioned PVA structures have been fabricated with low-coat single-step nanoimprinting methods, they will be widely applied for various tunable optical components by significantly reducing their production costs.
