Abstract in another language

We study nonlinear optics in plasmonic nanosystems, discuss the role of structural symmetries and the influence of linear optical properties. In particular, we investigate third harmonic generation from dimer nanoantennas and show that the nonlinear optical response, in contrast to common belief, is not governed by gap nonlinearities but fully described by the linear optical properties of the antenna. A simple nonlinear harmonic oscillator model is shown to reproduce all experimental features.
