We will present experimental studies and numerical modeling of nonlinear optical processes in plasmonic metamaterials based on assemblies of metallic nanorods and other complex geometries. Second- and third-order nonlinear optical response originating from a plasmonic component of the metamaterial will be discussed. Such plasmonic metamaterials can be used for engineering enhanced nonlinear optical properties with the required spectral and temporal response. We will also discuss a novel concept of an on-chip ultrafast all-optical modulator based on a hyperbolic metamaterial integrated in a silicon waveguide.
