双光子机制中的Mollow物理学显示出有趣的特征，例如光子对的路径控制时间重新排序，而无需延迟它们。在这里，我们分析计算的双光子关联$ g^{（2）}（\tau）$，必要的讨论和研究这种现象中的共振驱动的修饰态制度。结果表明，对于某些光谱选择光子对，g^{（2）}（\tau）-$函数存在上下界.最近报道的实验与所提出的理论相一致，从而表明共振驱动的四能级系统是量子级联装置中可操纵量子光的一个有趣的来源。我们还讨论了不太可能观察到反聚束的延迟时间$ \tau=0 $在激子-双激子相关函数在这样的实验中，因为反聚束源于不同的光子发射事件的相干和同相叠加。由于激光光子散射的发生，这种相干叠加态很容易受到扰动，产生关联函数g^{（2）}（0）=1。
Mollow physics in the two-photon regime shows interesting features such as path-controlled time-reordering of photon pairs without the need to delay them. Here, we calculate analytically the two-photon correlations $ g^{(2)}(\tau)$, essential to discuss and study such phenomena in the resonant-driven dressed-state regime. It is shown that there exists upper and lower bounds of the $ g^{(2)}(\tau)-$ function for certain spectrally-selected photon pairs. Recent reported experiments agree with the presented theory and thereby it is shown that the resonant-driven four-level system is an interesting source for steerable quantum light in quantum cascade setups. We furthermore discuss the unlikeliness to observe antibunching for the delay time $ \tau=0 $ in the exciton-biexciton correlation functions in such experiments, since antibunching stems from a coherent and in-phase superposition of different photon emission events. Due to the occuring laser photon scattering, this coherent superposition state is easily disturbed and leads to correlation functions of $ g^{(2)}(0)=1$.
