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.
