Abstract

In nature, most materials show analogous optical properties under RCP and LCP illumination, lead to distinguish from a right-handed (RCP) or left-handed circularly polarized (LCP) wave in both spatial and spectral domain by a conventional method is less efficient. Here, we present a meta-device which can resolve the handed of circular polarization and wavelength of incident light through diffraction angles. This work paves the road to a wide range of applications such as circular splitter and plasmon-enhanced circular dichroism spectra technology.
