We study the quantum kinetics of LO-phonon cascade emission in quantum wells by electron-hole pairs, whose relaxation ends with a trapping in quantum dots. Modulations with a period given by the LO-phonon frequency appear progressively in the time resolved differential transmission spectrum, indicating the transition from the quantum kinetic to the classical regime.
