Abstract
A device for detecting optical chirality includes a metasurface composed of a biperiodic array of nanodisks in the form of a checkerboard array [], where the nanodisks have diameters d±Δ/2 such that adjacent nanodisks [] have diameters that differ by an offset Δ. The nanodisks are composed of a dielectric material that is transparent and has a refractive index greater than 2 at a predetermined operational ultraviolet wavelength. The nanodisks have a width-to-height aspect ratio d/h tuned to produce spectral overlap of electric dipole and magnetic dipole modes of incident circularly polarized ultraviolet light.
