Exploiting Mie resonances in VO2 nanoantennas for achieving optically tunable metasurfaces in the visible range

Original language description

We study the optical properties of VO2 nanodiscs in the visible range. These nanostructures present strong Mie resonances not only in the known high-temperature, plasmonic phase, but also in the low-temperature phase, in which the material’s behavior is predominantly dielectric. A large extinction modulation is observed when the nanodiscs go upon phase transition. The nanodiscs present large potential for being used as building blocks of a metasurface which can be tuned by shining a CW laser on it.
