TL;DR: In this article, the coupling of CdTe quantum dots emission with ZnTe-based micropillar cavity modes was studied and a theoretical Purcell factor of 5.7 was derived.
Abstract: We study the coupling of CdTe quantum dots emission with ZnTe-based micropillar cavity modes. Nonresonant cavity mode feeding is reported together with an enhancement of the emission of a quantum dot thanks to resonant coupling with the cavity mode. The coupling is evidenced both in experiments with continuous and pulsed excitation. A theoretical Purcell factor is calculated and an experimental Purcell factor 5.7 is determined confirming the theoretical predictions. Additionally, we discuss the influence of the cascaded emission occurring under increased excitation power on the observed decay time of the excitonic transition.

TL;DR: In this article, an artificial atom coupled to a resonator of narrower emission linewidth opens a whole new field for quantum electrodynamics: they investigate such regime and evidence spectacular cavity pulling induced by a single quantum dot.
