A photoexcited tunable circular dichroism with planar chiral metamaterial in terahertz region

Abstract

We proposed a tunable planar chiral metamaterial (PCMM) which can achieve a giant and photoexcited tunable circular dichroism (CD) effect. The tunable PCMM is composed of an array of conjugated bilayer wheel structures integrated photoconductive silicon (Si). The conductivity of photoconductive Si pads filled in the gap of wheel structures can be tuned… (More)
