Active Tuning of High-Q Dielectric Metasurfaces by Liquid Crystals

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate active tuning of high-Q dielectric metasurfaces by embedding asymmetric silicon meta-atoms in liquid crystals, thus controlling the relative refractive index by heating. Spectral tuning of more than three resonance widths is achieved.
