Reconfigurable Flat Optics with Programmable Reflection Am- plitude Using Lithography-Free Phase-Change Materials Ultra Thin Films

Cueff, Sébastien Taute, Arnaud Bourgade, Antoine

We experimentally demonstrate a very large dynamic optical reflection modulation from a simple unpatterned layered stack of phase-change materials ultrathin films. Specifically, we theoretically and experimentally demonstrate that properly designed deeply sub-wavelength GeSbTe (GST) films on a metallic mirror produce a dynamic modulation of...
