Abstract

We report that in the absence of electric dipole contributions, upon azimuthal sample rotation, the corresponding SHG response was found to be chiral, i.e. it shows the presence of asymmetries with a sense of rotation (lack of mirror symmetry). It was found that this sense of rotation reverses with the handedness configuration (G and mirror-G, see Fig. 1). While it is apparent that the property originates in local field enhancements of electric and/or magnetic multipoles, its explanation invites further theoretical research.
