SC647: Nanophotonics: Design, Fabrication and Characterization
Nanophotonics is an emerging multidisciplinary field that deals with optics on the nanoscale. Recent progress in nanophotonics has created new and exciting technological opportunities. The interaction of light with nanoscale matter can provide unique functionality for photonic devices, and render unique information about their structural and dynamical properties. This nanophotonics course examines the key issues of optics on the nanometer scale. Starting with photonic crystal technologies, selected fabrication techniques will be identified and explained. Photonic devices that exploit nanoscale effects, such as nonlinear optical effects and quantum confinement, will be discussed. Various nanocharacterization techniques used in metrology, nondestructive evaluation, and biomedical applications will be explained.
