Phase-change photonic metamaterials
Phase-change photonic metamaterials
Chalcogenide phase-change media offer a uniquely functional and compositionally-controllable material base for photonic metamaterials. They variously present high-and low-index dielectric, low-epsilon and plasmonic properties at near-UV to near-IR wavelengths, coupled to a capacity for fast, non-volatile, electrically-/optically-induced switching between amorphous and crystalline phase states with markedly different properties (refractive index, resistivity, density, etc.). We present recent developments in their application to the engineering of switchable all-dielectric and plasmonic optical frequency metasurfaces and non-volatile mechanically reconfigurable nanostructures.

Abstract
Chalcogenide phase-change media offer a uniquely functional and compositionally-controllable material base for photonic metamaterials. They variously present high-and low-index dielectric, low-epsilon and plasmonic properties at near-UV to near-IR wavelengths, coupled to a capacity for fast, non-volatile, electrically-/optically-induced switching between amorphous and crystalline phase states with markedly different properties (refractive index, resistivity, density, etc.). We present recent developments in their application to the engineering of switchable all-dielectric and plasmonic optical frequency metasurfaces and non-volatile mechanically reconfigurable nanostructures.
