Surface Plasmon polaritons have long been utilized to enhance and confine optical fields at the nanoscale. They have been proven effective in the control and enhancement of optical processes at metal-dielectric boundaries with a variety of applications including nonlinear optics. In this paper we review the application of plasmonic metasurfaces to enhance non-linear processes on semiconductors, crystals, 2-D materials (graphene) and in the metal itself forming the metasurface. We consider applications such as harmonic generation, the generation of vortex beams, and the enhancement of nonlinear processes in 2D materials (graphene).
