Abstract

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.
