Abstract
The large field enhancement generated at the surface of a resonant plasmonic nanoparticle, or optical antennas, is the key mechanism that eventually led to the development of nonlinear plasmonics [1-2]. While the resonance may boost the nonlinear yield of an adjacent structure or surrounding medium, it was soon realized that optical antennas possess nonlinear coefficients comparable or exceeding those of standard nonlinear optical materials [3]. We discuss here two nonlinear optical processes - incoherent multi-photon luminescence (MPL) and coherent second-harmonic generation (SHG) – emitted from gold rod optical antennas upon local illumination with a tightly focused femtosecond near-infrared laser beam.
