Plasmonic Nanopatch Antennas as a Doubly Resonant Platform for Mode-Matched Second-Harmonic Generation

Plasmonic systems are advantageous for nonlinear optics as their ability to strongly confine and enhance the incident light can be exploited to boost the nonlinear interactions. In this contribution, we expand on the possibility of exploiting dielectric-loaded plasmonic film-coupled nanopatch antennas for an optimal second-harmonic generation.
