Fig. 3: Optical chirality of perovskite chiral metasurfaces.
From: Perovskite metasurfaces with large superstructural chirality
a Simulated differential optical chirality (integrated over the bottom surface) as a function of wavelength for a left-handed perovskite chiral metasurface, closely following the behavior of circular dichroism. b–e Color maps showing dissimilar spatial distributions of optical chirality for a left-handed chiral gammadion metamolecule at b 767 nm under LCP illumination, c 767 nm under RCP illumination, d 821 nm under LCP illumination, and e 821 nm under RCP illumination. All maps refer to the escaping surface upon which the light is incident.
