Origin of second harmonic generation in gold plasmonic nanostructures
Résumé
The second harmonic generation in gold nanoprisms is investigated numerically and experimentally. Comparing the experimentally obtained cartographic SHG maps with numerically simulated maps, we are able to discriminate between the different nonlinear source contributions as well as demonstrate the response that dominates in these nanostructures. Precisely, we show that the parallel surface current source dominates in these nanoprisms which has been a largely discarded source in the literature.
