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.
