Reconfigurable metal-dielectric nanodimers as component of hybrid nanophotonics

Abstract

Unification of plasmonics and all-dielectric nanophotonics in one system offers advantages in terms of light manipulation at nanoscale. In this work we demonstrate a novel type of asymmetrical hybrid nanostructures fabricated via combination of conventional lithographical methods with fs laser reshaping at nanoscale. The method of such type structures fabrication makes possible accurate engineering both electric and magnetic optical resonances of the hybrid nanoparticle. We apply this approach to a hybrid metasurface, demonstrating tuning of scattering properties and considerable shift of the resonant transmittance spectral position on 250 nm in the visible range.
