Abstract:
|
Recent advances in nanofabrication technology enable precise
patterning of various metallic nanostructures that can harness
electromagnetic surface waves known as surface plasmons, which
are electron density fluctuations that propagate along the metal
surface. By harnessing the strong coupling between photons and
the conduction electron plasma, the surface plasmon wave can
squeeze light into nanometer-scale volumes and increase
light-matter interactions, which can benefit many applications
in sensing, spectroscopy, imaging, data storage and
photovoltaics. This presentation will focus on new
techniques to fabricate plasmonic nanostructures with high
throughput, in particular periodic nanohole arrays and sharp
metallic tips, and their applications in biotechnology and
photonics.
