Abstract

Abstract : In article number 1910259, Andreas Tittl, Hatice Altug, and co‐workers develop tunable metasurfaces consisting of hybrid germanium and Ge3 Sb2 Te6 disk meta‐units. Switching the Ge3 Sb2 Te6 between its structural states enables dynamic light phase control with high transmittance. The versatility of these metasurfaces is demonstrated by optically programming spatial light phase distributions with single meta‐unit precision and retrieving high‐resolution phase‐encoded images over large‐areas.
