Abstract

We numerically studied a square array of plasmonic nanostructures with the unit cell composed of a z-shaped chiral structure and an achiral strip pair. Circular-polarization-dependent mode hybridization between the z-shaped structure’s radiant mode and the strip pair’s subradiant mode is observed: the resonance amplitudes of two hybrid modes are different for left-handed and right-handed circularly polarized waves, and an electromagnetically induced transparency-like transparency window is obvious for only one circularly polarized wave. Consequently, slow light with small group velocity is only evident for the corresponding polarization state.
