Area C - Topological Photonics

Topology as a new organizing principle opens up unprecedented possibilities in photonics, promising novel physics to be unraveled and exciting applications to be invented. Area C intends to explore topological states of light in both real and reciprocal space by designing and investigating novel single photonic devices and crystals. The main research objectives of Area C are related to the emergence of the optical Berry phase in photonic resonator devices, the properties and design of 2D and 3D photonic topological insulators, topological polariton and electric circuits – topological simulators based on exciton-polaritons and classical circuits, and chiral quantum networks with spins and photons on the basis of color quantum centers.
