Plasmonic antennas as design elements for coherent ultrafast nanophotonics
Abstract
The focus of ultrafast science is rapidly moving toward increasingly complex systems, both on a fundamental level (such as quantum networks in diamond or excitonic coherence in photosynthesis) and in applied physics (such as multiphoton microscopy in membranes and cells). However, to disentangle the heterogeneous contributions to dynamics in such complex structures, femtosecond time resolution needs to be accompanied by nanometric spatial excitation volumes. Here we present preengineered plasmonic structures to amplitude-phase shape excitation pulses in a designed way, and thus deliver simultaneous deterministic spatial and temporal control. We expect these results to establish the reproducibility that ultrafast plasmonics needs to serve as a reliable and accurate tool for the investigation of femtosecond nanoscopic dynamics in complex systems.
