Metallic and dielectric nanostructures provide distinct and unique means for shaping the electro-magnetic near field, and for channeling radiation from the far field to the nanoscale. The associated electromagnetic field hot spots can be exploited for the enhancement of interactions between light and matter, most prominently for surface-enhanced spectroscopy and sensing, the boosting of nonlinear interactions, and also for nanoscale spatial control over chemical reactions.
In my lecture I will give an introduction into the basic physics of the underlying electromagnetic and mixed light/matter modes in plasmonic (metallic), dielectric, and phonon-polaritonic systems, each providing unique light confinement opportunities from the UV to the mid-infrared part of the electromagnetic spectrum. Application examples in surface-enhanced Raman, fluorescence, and infrared absorption spectroscopy as well as nonlinear photonics and nanochemistry will be given.
