Abstract :
Polarization-dependent nondegenerate four-wave-mixing signal on a self-organized quantum-well material is measured and analyzed with seven-level density matrix description accounting for phase-space filling, excitation-induced dephasing and biexciton formation effects. It reveals these exciton-exciton interactions significantly influence polarization dependence.
