The versatile control of graphene’s plasmonic modes via an external gate-voltage inspires us to design efficient electro-optical graphene plasmonic logic gates at the mid-infrared wavelengths. We show that these devices are superior to the conventional optical logic gates because the former possess both cutoff states and interferometric effects. Moreover, the designed 6 basic logic gates (i.e. NOR/AND, NAND/OR, XNOR/XOR) achieved not only ultra-compact size-lengths of less than ?/28 with respect to the operating wavelength of 10µm, but also a minimum extinction ratio of as high as 15dB. These graphene plasmonic logic gates are potential building blocks for future nanoscale mid-infrared photonic integrated circuits.
