Abstract

Broken mirror symmetry of chiral structures imposes a lack of mirror symmetry in the scattering profile. When an energy dissipation channel is introduced in the system, an overall optical activity arises. Plasmonic nanostructures, therefore, are ideal platform to induce optical activity by means of consitutional or configurational chirality. We experimentally investigate mechanism of the plasmonically-induced configurational chirality in a periodic monoclinic hole array with a broken mirror symmetry. The resulting optical activity of the structure is studied by use of k-space leakage radiation measurements.
