Topological states of light have received significant attention due to the existence of counter-intuitive nontrivial boundary effects originating from the bulk properties of optical systems. Such boundary states, having their origin in topological properties of the bulk, are protected from perturbations and defects, and they show promises for a wide range of applications in photonic circuitry. The bulk-boundary correspondence relates the N-dimensional bulk modes to (N-1)-dimensional boundary… Expand
