Title: Electrically tunable all-dielectric optical metasurfaces based on liquid crystals

Abstract

We demonstrate electrical tuning of the spectral response of a Mie-resonant dielectric metasurface consisting of silicon nanodisks embedded into liquid crystals. We use the reorientation of nematic liquid crystals in a moderate applied electric field to alter the anisotropic permittivity tensor around the metasurface. By switching a control voltage ‘on’ and ‘off’ we induce a large spectral shift of the metasurface resonances, resulting in an absolute transmission modulation up to 75%. To the best of our knowledge, this is the first experimental demonstration of voltage control of a dielectric metasurface, paving the way for new types of electrically tunable metadevices, including dynamic displays and holograms.
