Abstract:
Embodiments of a monolithically integrated optical resonator are disclosed. In one embodiment, the optical resonator is a nanopillar optical resonator that is formed directly on a substrate and promotes a helically-propagating cavity mode. The helically-propagating cavity mode results in significant reflection or, in some embodiments, total internal reflection at an interface of the nanopillar optical resonator and the substrate even if refractive indices of the nanopillar optical resonator and the substrate are the same or similar. As a result, strong optical feedback, and thus strong resonance, is provided in the nanopillar optical resonator.
