Abstract
Metasurface, 2D counterpart of metamaterials, has been of great interests due to its capability of manipulating light’ properties such as amplitude, phase, polarization, and angular momentum. Individual property of light is quite freely modulated using metasurface; modulation of the several properties in single metasurface has been intensively explored. This multifunctional metasurfacs has a high potential to increase optical information channels of the optical data storage device. In this study, we propose duplex metasurface which contains structurally colored print and vectorial holograms with eight polarization channels. The encoded structural color prints can be observed under white light and the fully polarized holograms can be reconstructed using coherent laser source with combination of output polarizer/retarder. As a proof-of-concept, we devise optical security platform using our multifunction metasurface and propose detection device using liquid crystal (LC) cell.
