Graphene is a recently discovered new material with unique physical properties. In this paper we discuss its electrodynamic and optical properties. It is shown that the electromagnetic response of graphene to the external radiation is strongly nonlinear and such phenomena as the frequency harmonics generation and frequency mixing effects can be observed in it. The nonlinear susceptibility of graphene is higher than that of many other materials.We predict that under certain conditions the plasmon enhanced second harmonic generation can be observed in graphene.

Nonlinear Optical Process

Here, we propose a novel plasmonic structure, called asymmetric plasmonic nanocavity grating (APNCG), which is shown to dramatically enhance nonlinear optical process of second harmonic generation (SHG). The proposed structure consists of two different metals on both sides of lithium niobate and a thin layer of graphene. By using two different metals the nonlinear susceptibility of the waveguide would be increased noticeably causing to increase SHG. On the other hand, it consists of two identical gratings on one side. By two identical gratings, the pump beam is coupled to two opposing SPP waves, which interfere with each other and result in SPP standing wave in the region between the two gratings. The distance between two gratings will be optimized to reach the highest SHG. It will be shown that by optimizing the geometry of proposed structure and using different metals, field enhancement in APNCG waveguides can result in large enhancement of SHG.
