Nanophotonics deals with structured materials on the nanoscale for the
manipulation of light. Photonic crystals and plasmonic metamaterials are hot
topics in contemporary photonics. The properties of these materials can be designed to a significant extent via their structure. Many of the properties of these nanostructured materials can be understood from their dispersion diagram or optical bandstructure, which is a core tool that will be explored in the module. Familiar concepts such as optical waveguides and cavities, multilayer mirrors and interference effects will be used to explain more complex features such as slow light propagation and high Q cavities in photonic crystal waveguides. Propagating and localised plasmons will be explained and will include the novel effects of
super-lensing and advanced phase control in metamaterials.
