N2 - We numerically demonstrate that spatially and temporally phase-shaped ultrafast laser pulses can spatiotemporally control ultrafast plasmon pulses generated at metal nanostructures. Excitation laser pulses designed by the superposition of high-order Hermite–Gaussian modes can localize the plasmon excitation at desired areas in nanostructures, and at the same time the temporal plasmon evolution is determined by the excitation pulse shape and the local plasmon response function. We numerically demonstrate this control scheme for local plasmons at the Au nanostructures and a surface plasmon polariton waveguide.
