We investigate nonlinear optical second- and third-harmonic generation from graphene covered on dielectric gratings. The nonlinear optical response in graphene is dramatically enhanced when surface plasmon of graphene is excited. Compared with graphene on a flat dielectric, the enhancement factor of...
