However, single layer metasurface systems consisting of two-dimensional nanoparticle arrays exhibit only a weak spatial asymmetry perpendicular to the surface and therefore have mostly symmetric transmission features. Here, we present a metasurface design principle for nonreciprocal polarization encryption of holographic images. Our approach is based on a two-layer plasmonic metasurface design that introduces a local asymmetry and generates a bidirectional functionality with full phase and amplitude control of the transmitted light. The encoded hologram is designed to appear in a particular linear cross-polarization channel, while it is disappearing in the reverse propagation direction. Hence, layered metasurface systems can feature asymmetric transmission with full phase and amplitude control and therefore expand the design freedom in nanoscale optical devices toward asymmetric information processing and security features for anticounterfeiting applications.","lang":"eng"}],"volume":19,"author":[{"full_name":"Frese, Daniel","last_name":"Frese","first_name":"Daniel"},{"first_name":"Qunshuo","full_name":"Wei, Qunshuo","last_name":"Wei"},{"first_name":"Yongtian","last_name":"Wang","full_name":"Wang, Yongtian"},{"full_name":"Huang, Lingling","last_name":"Huang","first_name":"Lingling"},{"last_name":"Zentgraf","full_name":"Zentgraf, Thomas","first_name":"Thomas","orcid":"0000-0002-8662-1101","id":"30525"}],"status":"public","publication_identifier":{"issn":["1530-6984","1530-6992"]},"intvolume":"        19","_id":"11953","year":"2019","page":"3976-3980","type":"journal_article","issue":"6","publication":"Nano Letters","date_created":"2019-07-15T07:55:26Z"}
