"Taming Light at the Nanoscale"
Harnessing, processing, guiding, and storing light at the nanoscale are at the
cornerstones of the development of science and technology. Rapid progress of such
manipulation of light in the future critically depends on the potential to enhance the
performance, functionality, and miniaturization of key optical devices. In this talk we
will give an overview of our recent achievements in exploring light interaction with
plasmonic and metamaterial nanostructures; we will discuss possibilities for utilizing
material’s response to harness light, and will show novel physics emerging at the
intersection of different areas of optical science brought together at the nanoscale. We
will focus on three general themes: (1) light propagation and self-control in nonlinear
plasmonic nanometer-size waveguides, in which phenomena such as plasmon self-focusing,
soliton formation, and plasmon-to-plasmon second harmonic generation may occur, (2)
symmetry and symmetry breaking within the fraction of a wavelength, where we will discuss
various scenarios for breaking spatial and time-reversal symmetry with individual
plasmonic nanostructures and within the waveguides, and will show such effects as one-way
wave propagation and nonreciprocal optical power flow circulation, and (3) electric and
magnetic control over the light propagation and its interaction with the matter, where we
elaborate novel mechanisms for steering electromagnetic response.
