Abstract: (2224 Views)
In this paper first we derive equation of CW wave propagation in graphene nonlinear directional coupler by using first order perturbation theory. By simulation of the wave propagation we have shown that it can be reached to an all optical self-switch within .3-7µWatt/mm at the length of 1.2µm. In this calculation it is supposed that the nonlinear effects and each graphene layer has affected as perturbation on the other layer but have no effect on each layer.
