Abstract

We propose to use a 1-atom-thick structure, i.e., a single graphene sheet for the dynamic control of an Airy plasmon (AiP). The graphene layer serves not only as the guiding medium but also as the modulator for the AiP. By altering the external biased voltage, the effective mode index for surface plasmon waves can be modified. Consequently, the deflection and the propagation distance of the AiP are controlled dynamically. Due to the advantages of graphene plasmons, graphene AiPs may lead to compact and flexible AiP devices. This paper could be also beneficial to relevant applications such as tunable plasmonic optical routing and on-chip signal processing.
