Abstract

Electron beam induced deposition (EBID) is used to grow on a transparent substrate plasmonic antennas formed by gold nanorods. We first discuss the influence of the growth parameters on the geometrical homogeneity of the structures. The optical response of optimized rods with different aspect ratios are measured using scattering spectroscopy. The optical data show antenna resonances in good agreement with 3D numerical simulations for pure gold antennas, validating EBID as a novel relevant technique for the fabrication of plasmonic nanostructures.
