All-optical switching of photonic metamaterials enabled by surface-mediated phase transitions in gallium
All-optical switching of photonic metamaterials enabled by surface-mediated phase transitions in gallium
Reversible, optically-induced surface metallization in a nanoscale layer of elemental gallium forming the backplane of a photonic metamaterial absorber provides a mechanism for a strong, resonantly enhanced reflective optical nonlinearity at µW/µm2 intensities.
