Varifocal metalens using tunable and ultralow-loss dielectrics

Varifocal metalens using tunable and ultralow-loss dielectrics

The field of flat optics that uses nanostructured, so-called metasurfaces, has seen remarkable progress over the last decade. Chalcogenide phase-change materials (PCMs) offer a promising platform for realizing reconfigurable metasurfaces, as their optical properties can be reversibly tuned. Yet, dem...
