Název v původním jazyce

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

Popis výsledku v původním jazyce

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.
