Electrically driven reprogrammable phase-change metasurface reaching 80% efficiency

Electrically driven reprogrammable phase-change metasurface reaching 80% efficiency

The authors demonstrate an efficient platform for electrically driven reconfigurable metasurfaces by using Ge2Sb2Te5 to realize non-volatile, reversible, multilevel, and fast optical modulation and wavefront engineering in the near-infrared spectral range.
