    We summarize our recent results regarding the control and optimization of the second-order nonlinear response of plasmonic metamaterials. Such materials consist of arrays of metal nanoparticles, where the plasmonic resonances of individual particles depend on the size, shape, and dielectric environment of the particles. The resonances are further influenced by the coupling of the particles through the array. We first show that the second-order response, as determined by secondharmonic generation is significantly enhanced by the state-of-the-art sample quality and the resulting narrow plasmonic resonance lines.We then show that the response can depend on subtle details of the ordering of the particles in the array, with apparently similar orderings resulting in second-harmonic generation responses that differ by a factor of 50. Finally, we show that the response can be enhanced by complementing the second-harmonic active particles with passive elements that have no nonlinear response as such. Our results are important in developing metamaterials with tailorable nonlinear properties.
