We study self‐induced coherence (SIC) in a system composed of two coupled quantum dots (QDs). SIC consists in a coherent transfer of excitation between two systems (atoms or QDs) resulting from their collective interaction with the quantum electromagnetic vacuum. This leads to population trapping in a delocalized, optically inactive state. We focus on the effect of a difference in transition energies and coupling between the two emitters on the evolution of exciton occupation in the two QD system.
