Ring-shaped one-, two-, and three-bit plasmonic logic gate configurations and circuits have been proposed, which, besides being compact, are also versatile and can be easily cascaded, the output logic values being controlled by both the geometry of the multi-port rings and the phase of the incident beams. This latter degree of freedom, not fully exploited up to now in plasmonic circuits, offers a high degree of flexibility of logic gate configurations.
