A. Belardini et al. find that hybrid structures composed by self-ordered dielectric nanospheres partially covered by gold nanocrescents produce an efficient second harmonic generation signal due to the cooperative effect of localized plasmon excitation and a 2D Bragg grating. Asymmetries in the geometric shape of the gold nanocrescents induce a circularly polarized optical response.
