We illustrate the possibility of manipulating light in the nanoscale using the combination of plasmonics physics with concepts and tools developed for coherent control of molecular dynamics. Phase and polarization control are applied to guide electromagnetic energy through metal nanoparticle junctions and control its branching ratios at array intersections. Optimal control theory is applied as a design tool, to develop constructs with desired functionality. We suggest also that nanoplasmonics could be used to make spatially localized light sources with predesigned coherence and polarization properties, which could serve to coherently control individual nano-systems.
