Simulation of the second harmonic response from hybrid plasmonic nanoantennas — •Yevgen Grynko1, Jens Foerstner1, Heiko Linnenbank2, and Stefan Linden2 — 1University of Paderborn, Paderborn, Germany — 2University of Bonn, Bonn, Germany
Experimental spectroscopy of hybrid metallic/dielectric nanogap-antennas shows twofold enchancement of the SHG signal in comparison to pure metallic nanoantennas. Here, we study numerically their linear optical properties and the origin of the SHG emitted from such structures. We use the Discontinous Galerkin Time domain method and Maxwell-Vlasov hydrodynamic approach to describe the nonlinear flow of the free electron gas in a metal [1].
