Project title: Light-matter interactions in photonic topological metamaterials
Supervisor: Dr Vincenzo Giannini and Professor Richard Craster
Photonic topological insulators (TIs) are a new class of material that promise greater control over the interactions between light and matter . In particular, the edge states at the interfaces between photonic TIs and trivial materials are both robust (topologically protected) and spin-polarised (edge states of opposite spin travel in opposite directions) . This project will investigate whether these novel properties of photonic TIs and their edge states can be exploited in the design of metamaterials for enhanced imaging and sensing applications.
