Giant Chiral Optical Response from a Twisted-Arc Metamaterial

We demonstrate enormously strong chiral effects from a photonic metamaterial consisting of an array of dual-layer twisted-arcs with a total thickness of ∼λ/6. Experimental results reveal a circular dichroism of ∼0.35 in the absolute value and a maximum polarization rotation of ∼305°/λ in a near-infr...
