We investigate the nonlinear emission of non-centrosymmetric plasmonic nanoantennas with polarization-resolved nonlinear microscopy. We reveal a cascade process between a pump and a second harmonic photon that contributes to the overall third harmonic generation.

Abstract
We investigate the nonlinear emission of non-centrosymmetric plasmonic nanoantennas with polarization-resolved nonlinear microscopy. We reveal a cascade process between a pump and a second harmonic photon that contributes to the overall third harmonic generation.File in questo prodotto:
