The photoluminescence (PL) kinetics of heterostructures with InP self‐assembled quantum dots are studied under quasi‐resonant pulse excitation in the presence of an external electric field. An oscillatory behavior of the PL kinetics is shown to arise due to quantum beats of the radiative states. A model of the coherent excitation of nonresonant PL is proposed.
