1. An optical integrated light source, comprising:
a plurality of topological ring resonators, each of the topological ring resonators being 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, wherein the topological ring resonators are each concentrically arranged with respect to one another; and
a magnetic material 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 orbital angular momentum.
