"Self-Assembled Colloidal Plasmonic Systems"
Jonathan Fan, Harvard University
Abstract The self-assembly of colloids is an alternative to top-down
processing that enables the fabrication of nanostructures. I will show that
self-assembled clusters of metal-dielectric spheres are the basis for
nanophotonic structures. By tailoring the number and position of spheres in
close-packed clusters, plasmon modes exhibiting strong magnetic and
Fano-like resonances emerge. The use of identical spheres simplifies cluster
assembly and facilitates the fabrication of highly symmetric structures.
These types of chemically synthesized nanoparticle clusters can be
generalized to other two- and three-dimensional structures and can serve as
building blocks for new metamaterials.
bio Jonathan Fan is currently a Postdoctoral Research Associate in the
Capasso Group at Harvard University. He received his PhD in Applied Physics
from the Capasso Group in 2010, where he was an NSF Graduate Fellow doing
plasmonics research in colloidal systems and quantum cascade laser waveguide
design. He received his BS with highest honor in Electrical Engineering
from Princeton in 2004. He has authored and co-authored 18 papers.
