Abstract

Photoluminescence experiments were performed on high-quality InGaAs/GaAs periodic multiple quantum well structures with up to N = 100 quantum wells, where the exciton emission is strongly influenced by the coherent interwell coupling, showing up in multiple linesplitting and a crossing of the normal modes around Bragg resonance. For N≥30 and a certain distance between adjacent wells, a quadratic increase of the amplitude and an increasing directionality of the vertical emission are observed. The weakest emission occurs in Bragg resonance, where under resonant excitation, a strong superradiant reemission takes place.
