چکیده
|
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 second- and third-harmonic generation is up to 106 and 108, respectively. we, in detail, studied the second- and third-harmonic generation intensity influenced by the angle of incidence, the fermi level, and carrier mobility of graphene.
