All-dielectric phase-change reconfigurable metasurface

All-dielectric phase-change reconfigurable metasurface

We harness non-volatile, amorphous-crystalline transitions in the chalcogenide phase-change medium germanium antimony telluride (GST) to realize optically-switchable, all-dielectric metamaterials. Nanostructured, subwavelength-thickness films of GST present high-quality resonances that are spectrall...
