We introduce a computational Maxwell-Bloch framework for investigating out of equilibrium optical emitters in open cavity-less 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 systems of quantum dots with diﬀerent density and dipolar coupling. We observe that signatures…
