In this paper, all-optical switches using a novel combination of graphene and insulator-metal plasmonic waveguides are proposed. For the proposed switches the optical Kerr effect is used to change the chemical potential of graphene-based plasmonic waveguides which are located in arms of a Mach-Zehnd...
