In this paper, all-optical switches based on plasmonic square ring resonator (PSRR) with smooth corner bends have been proposed. Both three and four ports nonlinear switches have been numerically analyzed and simulated by the finite-difference time-domain (FDTD) method. By applying Kerr nonlinear self-phase modulation (SPM) effect, it has been shown that in four port switches the output power ratio of 12.77dB can be achieved by the switching power of 11.84 (kW/m), whereas the switching power of 12 (kW/m) is needed for attaining the power ratio of 16.8dB in three port switches. PSRRs are suitable for using in photonic integrated circuits as all-optical switches because of their nanoscale size and low required switching power.
