Vector pulse shaped ultrafast Plasmon based on response functions measured for orthogonally polarized excitation

Abstract

For spatiotemporal vector pulse control of local plasmon at gold nanostructures, plasmon response functions at orthogonally polarized ultrafast laser excitation are measured by an electrical-field cross-correlation imaging method using a dark-field microscope. By shaping the vector pulse of the excitation laser, arbitrarily shaped plasmon vector pulses can be generated.
