We analyze the spontaneous and stimulated optical decay of states with two electron–hole pairs virtually excited by optical pumping. We find that the photon pairs from the spontaneous fission in bulk large‐gap semiconductors and in semiconductor microcavities exhibit quantum features which can be observed by coincidence detection.
