Cavities with nonspherical mirrors for enhanced interaction between a quantum emitter and cavity photons
Cavities with nonspherical mirrors for enhanced interaction between a quantum emitter and cavity photons
We propose a procedure for the significant enhancement of the strong-coupling rate between photons in an optical cavity and a single quantum emitter, such as an atom, quantum dot, or trapped ion. We show that specially designed, nonspherical mirrors can lead to cavity eigenmodes that exhibit a large field enhancement at the center of the cavity while inducing significantly less beam divergence and therefore smaller round trip losses and higher cooperativity than can be achieved by operating a spherical-mirror cavity in the near-concentric regime. We verify our designs using mode matching theory and discuss their robustness relative to different kinds of manufacturing deviations.

Abstract
We propose a procedure for the significant enhancement of the strong-coupling rate between photons in an optical cavity and a single quantum emitter, such as an atom, quantum dot, or trapped ion. We show that specially designed, nonspherical mirrors can lead to cavity eigenmodes that exhibit a large field enhancement at the center of the cavity while inducing significantly less beam divergence and therefore smaller round trip losses and higher cooperativity than can be achieved by operating a spherical-mirror cavity in the near-concentric regime. We verify our designs using mode matching theory and discuss their robustness relative to different kinds of manufacturing deviations.
