Influence of graphene-based hyperbolic metasurface parameters on the second harmonic generation

We have investigated the influence of graphene-based hyperbolic metasurface parameters such as the structure periodicity, the ribbon’s width, the graphene chemical potential and the frequency of exciting light on the second harmonic generation phenomenon. The investigation showed that this process may be observed just for a fixed angle of the surface plasmon-polaritons propagation. Taking into account the possibility to control graphene properties (i. e., its chemical potential, or Fermi level) by the gate voltage, for example, our results may became the basis for non-linear optical reconfigurable devices.
