Correlated triple hybrid amplitude and phase holographic encryption based on a metasurface
文献摘要：
Metasurface holography is becoming a universal platform that has made a considerable impact on nanophotonics and information optics,due to its advantage of large capacity and multiple functionalities.Here,we propose a correlated triple amplitude and phase holographic encryption based on an all-dielectric metasurface.We develop an optimized holographic algorithm to obtain quantitatively correlated triple holograms,which can encrypt information in multiple wavelength and polarization channels.We apply the"static"and"dynamic"pixels in our design,respectively.Two kinds of isotropic square nanofins are selected,one functioning as a transmitter and the other functioning as a blocker counterintuitively at both working wavelengths,while another anisotropic rectangle nanofin can transmit or block light in co-polarization selectively,mimicking"dynamic"amplitude switches.Meanwhile,such"dynamic"nanofins can simultaneously function as a phase modulator in cross-polarization only at the transmission wavelength.That is,through smart design,different dielectric meta-atoms functioning as spectral filters as well as phase contributors can compositely achieve triple hybrid amplitude and phase holograms.Such strategy promises to be applied in compact large-capacity information storage,colorful holographic displays,optical encryption,multifunctional imaging devices,and so on.
