研究目的
Investigating the quantum dynamics and stability of a two-level emitter in a resonant microcavity with optical feedback provided by a distant mirror, focusing on stabilizing the emitter-microcavity subsystem.
研究成果
The study identifies a steady state in the one-excitation subspace where the state initialized in the microcavity and quantum dot degrees of freedom is stable against decay into external cavity photons. Stability analysis indicates that additional solutions arise above a critical value of the ratio between the microcavity photon damping rate and the quantum dot–microcavity coupling strength, showing similarities to the Lang-Kobayashi model.
研究不足
The study focuses on the one-excitation subspace and assumes 100% reflection from the distant mirror. The effects of time delay are studied for various external cavity lengths, but other parameters like quantum dot dephasing rate and decay rate are not considered.
