我们提出了两个量子点和不对称微柱腔之间偏振依赖的强耦合机制的实验和理论结合研究。光致发光发射表明，基腔模式分为两个线偏振腔模式，这两个模式都耦合到45%对齐的量子点激子。我们绘制了各种单激子和双激子耦合机制，包括双激子在x和y探测角下的全能量色散和双腔发射。为了解释复杂的光-物质耦合，我们应用了一种分析光子格林函数方法，成功地再现了我们实验数据的定性特征。
We present a combined experimental and theoretical study of the polarization-dependent strong-coupling regime between two quantum dots and an asymmetric micropillar cavity. The photoluminescence emission demonstrates that the fundamental cavity mode is split into two linearly polarized cavity modes, both of which are coupled to 45%-aligned quantum dot excitons. We map out various single-exciton and double-exciton coupling regimes, including the full energy dispersion of dual-exciton and dual-cavity emission under x and y detection angle. To explain the complex light-matter coupling we apply an analytical photon Green function approach that successfully reproduces the qualitative features of our experimental data.
