Boston Chapter of the IEEE Photonics Society

Abstract:  This talk introduces and reviews new ideas and recent progress in coherent, nonlinear and ultrafast nanoplasmonics. It includes a brief Introduction to the topic and forefront, focus areas based partially on original contributions, including ultrafast, coherent, nonlinear, and stimulated phenomena. Spaser will be one of the focus points of the talk as an ultrafast generator of local optical field on nanoscale.  We will discuss nanolenses built of metal nanosphere and tapered polaritonic waveguides as concentrators of optical energy on nanoscale. Theory of surface-enhanced Raman scattering (SERS) is one of the focal points of the talk. We also consider dynamic, controllable, ultrafast localization of optical energy on the nanoscale and nonlinear photoelectron emission coherently controlled by the phases of the ultrashort excitation pulses. We also consider a recent development based on the combination of the adiabatic concentration of optical energy on nanoscale and spatio-temporal modulation of surface plasmon polaritons. Finally, we discuss extreme nanoplasmonics where phenomena develop on the spatial scale of a few nanometers and temporal scale of hundreds attoseconds. We present both theory and available experimental data, and discuss applications of nanoplasmonics.
