Abstract
A study was performed to determine the extent cavity enhancement may increase single-photon production while maintaining single-photon purity. It was found that certain combinations of cavity lifetime and light-matter coupling strength can lead to carrier-photon correlations that increase single-photon generation rate while maintaining low 2nd order photon correlation. This study provides guidance for future emitter-cavity design to achieve high purity and ultrafast single photon generation.
