Abstract
An optical integrated light source includes a plurality of topological ring resonators. Each of the topological ring resonators is defined by an interface between two distinct periodic structures having different topological invariants such that a one-way edge mode may be excited along the interface. A magnetic material is arranged to interact with the plurality of topological ring resonators such that the optical integrated light source is structured and configured to generate plural beams each carrying large orbital angular momentum.
