Modes interplay controls the second harmonic generation dynamics of plasmonic nanostructures

Olivier Martin, Gabriel David Bernasconi, Andrei Kiselev

A large amount of experimental and theoretical works deals with the second harmonic generation from different plasmonic geometries. Since they often consider relatively long optical pulses, many of these studies are focused on the investigation of a quasi- ...
