Abstract
Surface plasmon polaritons (SPPs) with vortex phase distribution, known as plasmonic vortices, play an important role in several research fields. However, the ultrafast modulation for the single plasmonic vortex and vortex arrays excited by ultrafast laser, have yet to be studied. Here, we theoretically investigate the properties of single plasmonic vortex and plasmonic vortex array excited by femtosecond pulses using analytical and FDTD simulations. The ultrafast plasmonic vortex/array is excited by a slit (ring-shaped/hexagonal) on a gold film, and the incident light consists of two time-delayed femtosecond sub-pulses carrying the same topological charge but orthogonal circular polarization. By modulating the topological charge of incident pulses, the dynamics of time-varying electric field and energy flow in the ultrafast plasmonic vortex and array can be observed, such as the merging of multiple energy-flow loops and variations in ultrafast transitions between the light fields of the four six-fold symmetries. This work could offer new approaches for ultrafast on-chip optical information processing and multiparticle trapping.
