Abstract

A photonic system includes a passive optical cavity and an optical waveguide. The passive optical cavity has a preferred radial mode for light propagation within the passive optical cavity. The preferred radial mode has a unique light propagation constant within the passive optical cavity. The optical waveguide is configured to extend past the passive optical cavity such that at least some light propagating through the optical waveguide will evanescently couple into the passive optical cavity. The passive optical cavity and the optical waveguide are collectively configured such that a light propagation constant of the optical waveguide substantially matches the unique light propagation constant of the preferred radial mode within the passive optical cavity.
