Broadband tunable nonlinear optical response in plasmonic metamaterials -INVITED

Nanostructured materials with tunable nonlinear optical response are of great interest for different applications in nanophotonics.In thiswork wereport the results ofa comprehensive study onthe nonlinear optical properties of two kinds of plasmonic metamaterials, i.e., honeycomb nanoprism arrays and multilayer hyperbolic metamaterials, which proved to havea very rich spectrum of parameters(asmetamaterials morphology and composition, wavelength and polarization of an input beam)to exploitforcontrollingtheir nonlinear responseover a broad spectral range.
