Chiro-optical response in helically arranged achiral dielectric nanoparticles

Abstract

We demonstrate experimentally how achiral dielectric nanoparticles when arranged in a chiral geometry can exhibit chiro-optical activity. Such a response originates in the dynamic electromagnetic interactions between the resonant modes of the individual nanoparticles, as confirmed by numerical simulations. When extended in an infinite periodic array, additional chiro-optical bands were induced at the lattice/collective modes of the nanoparticle system which have been experimentally observed. Our fabrication method is wafer scale and the material platform is low loss and CMOS-compatible, which together can allow a seamless integration of this novel material system to existing optoelectronic technologies.
