Abstract

We demonstrate theoretically and experimentally a chiral-selective plasmonic absorber by utilizing eng -shaped-resonators in the visible frequencies. Our metasurface design enables chiral-selective absorption bands, in which absorption peaks for left-handed circularly polarized and right-handed circularly polarized occur at different resonance wavelengths resulting in significant circular dichroism (CD). Both simulated and measured absorption spectra exhibit maximum absorptions exceeding 80% associated with a CD value of ∼0.5. Such a chiral plasmonic metasurface absorber with high performance could find applications in optical filters, non-linear optics, thermal emitters, and hot-electron collection devices.
