Chalcogenide reconfigurable metamaterials
Chalcogenide reconfigurable metamaterials
Chalcogenide semiconductors offer a unique compositionally-controllable material base for reconfigurable metamaterial applications. They present high and low-index dielectric, low-epsilon and plasmonic properties across UV to IR wavelengths, in addition to fast, non-volatile, electrically/optically induced phase-change capability between states with markedly different properties. We present our recent advances in their application to non-volatile reconfiguration in metamaterials, including: switchable ‘colors’ through reversible dielectric-plasmonic transitions; the first reconfigurable UV/HEV dielectric metamaterials, wherein the chalcogenide is hybridized with a high-index dielectric supporting the resonant mode; and the integration of such materials on the tip and side of optical fibres for dynamic dispersion control.

Abstract
Chalcogenide semiconductors offer a unique compositionally-controllable material base for reconfigurable metamaterial applications. They present high and low-index dielectric, low-epsilon and plasmonic properties across UV to IR wavelengths, in addition to fast, non-volatile, electrically/optically induced phase-change capability between states with markedly different properties. We present our recent advances in their application to non-volatile reconfiguration in metamaterials, including: switchable ‘colors’ through reversible dielectric-plasmonic transitions; the first reconfigurable UV/HEV dielectric metamaterials, wherein the chalcogenide is hybridized with a high-index dielectric supporting the resonant mode; and the integration of such materials on the tip and side of optical fibres for dynamic dispersion control.
