Cooperative exciton–photon dynamics of a linear chain of quantum dots in a perfect microcavity

Cooperative exciton–photon dynamics of a linear chain consisting of closely spaced quantum dots has been studied numerically in the simplified Jaynes–Cummings model with dipole–dipole interaction and only nearest neighbor interactions. In the aggregate, quantum dots are assumed to be coupled with a single mode field of a perfect microcavity. In the chain, the transport of the excitation energy via resonance dipole–dipole interaction generates propagating exciton-waves which interfere with themselves in the mediation of photon field. We show that the absorption and emission of the field is inhibited or enhanced depending on system parameters and the excitation of specified quantum dots is also suppressed or enforced depending on dipole–dipole coupling constant.
