Abstract :
Three-dimensional patterning of gold nano-particles on SiO2 and Si substrates is performed by ion-beam lithography with 15-20 nm resolution. Realization of an on-demand achiral and chiral modifications of nano-structures are demonstrated. Simulations of optical properties of the obtained nano-architectures reveal the possibility to tailor the field enhancement both in the spatial and spectral domains, which are foreseen to be applicable for light harvesting and opto-mechanics at nanoscale.
