Abstract

Surface plasmon polaritons (SPPs) are tightly confined waves along an interface between a metal and a dielectric. Because they are subwavelength in nature, light can be concentrated in subwavelength volumes, which is of particular interest to nonlinear optics. Up to now, most proposals of nonlinear plasmonic systems, including artificially structured metamaterials incorporating plasmonic components, have neglected the metal nonlinearity and assumed that the dielectric is the primary contributor to the nonlinear response [1,2].
