Topological photonic crystal nanocavity laser [PDF]
Communications Physics, 2018 Topological edge states exist at the interfaces between two topologically distinct materials. The presence and number of such modes are deterministically predicted from the bulk band topologies, known as the bulk-edge correspondence.
