Adiabatic Concentration and Coherent Control in Nanoplasmonic Waveguides

We describe ideas and results of controlling surface plasmon polaritons (SPPs) in nanoplasmonic waveguides. The adiabatic concentration of the optical energy in tapered nanoplasmonic waveguides is presented as a universal approach to transfer of energy and coherence from macroor microscale to the nanoscale. Coherent control allows for directed and dynamically-defined concentration of the optical energy on nanometer-femtosecond spatio-temporal scale.
