The past decade has witnessed a revolution in optical science brought about by major
advances in our ability to manipulate light with nanometer scale components. The
surface plasmons of metallic structures have been key to many of these advances. Our
understanding of the interaction of surface plasmons in complex nanosystems, in
particular reduced-symmetry nanostructures, has led to new capabilities ranging from
ultrasensitive detection schemes for sensing to new devices, even plasmon-based logic
gates. New regimes for optical systems, such as within living cells or integrated into
photovoltaic device designs for harvesting solar energy, have emerged from this research.
We will highlight some of the important advances in fundamental nanoscale optics and
their resulting applications in our presentation.
