Abstract

We have demonstrated the directional control of surface plasmon polariton (SPP) waves propagating through an asymmetric plasmonic Bragg resonator using femtosecond temporal-phase control via the resonant coupling of SPPs and the interference of SPPs. The near-field images display significant temporal-phase dependence, switching between left and right propagation after the Bragg resonator. Our results would be a key step toward the control of surface plasmon propagation direction in nanoscaled plasmonic applications
