Abstract
Monolithically integrated optical resonators are disclosed. An optical resonator may be a nanopillar optical resonator that is formed directly on a substrate and promotes a helically-propagating cavity mode. The helically-propagating cavity mode may result in significant reflection or, 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, may be provided in the nanopillar optical resonator.
