Abstract :
We discuss various mechanisms that are important in optimizing the second-order nonlinear optical response of metamaterials based on arrays of plasmonic metal nanoparticles. The response is enhanced by high quality particle resonances as well as interparticle coupling through the lattice. In addition, geometrical effects may play an unexpected role, superseding straightforward resonant effects.
