Paper Abstract

In this work, we demonstrate superchiral light generation based on achiral plasmonic surfaces. At resonance, the symmetric cavity-coupled plasmonic system generates single-sign chiral near-field whose helicity is determined solely by the handedness of the incident light. We elucidate the mechanism for such unique superchiral near field generation and find its origin in coherent and synergetic interactions between plasmonic and photonic cavity modes. The cavity-coupling enhances otherwise weak plasmonic chiral near-field by many folds. Furthermore, the system in a unique way suppresses the far field chirality due to its totally symmetric geometry providing a route for surface-enhanced chiroptic spectroscopy on a single surface.
