论文摘要
我们介绍了一个计算麦克斯韦框架，用于调查开放系统中的不平衡光学发射器。为此，我们从基本的光 - 物质相互作用中计算了每个发射极的脉搏诱导的动力学，并自愿计算它们的辐射耦合，包括传播效应产生的相位不均匀性。该半经典框架应用于具有不同密度和偶性耦合的打开量子点系统。我们观察到超级行为的特征，例如方向性和更快的衰减，以及次级发射。我们比较并讨论使用我们的方法和主方程方法获得的计算光发射。我们的框架可以在时间域中对大型光学合奏进行定量研究，并可用于设计具有增强的超级和次值属性的新系统。
We introduce a computational Maxwell-Bloch framework for investigating out-of-equilibrium optical emitters in open systems. To do so, we compute the pulse-induced dynamics of each emitter from fundamental light-matter interactions and self-consistently calculate their radiative coupling, including phase inhomogeneity from propagation effects. This semiclassical framework is applied to open quantum dots systems with different densities and dipolar coupling. We observe signatures of superradiant behavior, such as directionality and faster decay, as well as subradiant emission. We compare and discuss the computed light emission obtained with our method and a Master equation approach. Our framework enables quantitative investigations of large optical ensembles in the time domain and could be used to design new systems with enhanced superradiant and subradiant properties.
