Regular array of plasmonic nanoantennas (nanocrescents) can be easily produced by grazing evaporating gold on a self-ordered surface formed by hexagonal arrangements of polystyrene nanospheres, thus realising a hybrid plasmonic-photonics nanostructures (HPPN). By using second harmonic generation (SHG) technique we experimentally demonstrated that asymmetry in the shape of the nanoantennas induces an optical chiral response of the whole sample.

Abstract
Regular array of plasmonic nanoantennas (nanocrescents) can be easily produced by grazing evaporating gold on a self-ordered surface formed by hexagonal arrangements of polystyrene nanospheres, thus realising a hybrid plasmonic-photonics nanostructures (HPPN). By using second harmonic generation (SHG) technique we experimentally demonstrated that asymmetry in the shape of the nanoantennas induces an optical chiral response of the whole sample.
