摘要：

We have observed quantum beats in the exciton emission of type II quantum wells. The beats are observed in linear or circular polarization, provided the excitation is linearly polarized along 〈1 0 0〉 or 〈0 1 0〉 or is circular polarized. The experimental data show a macroscopic lifting of the axial symmetry of the exciton. The observed beat frequency corresponds to an energy splitting of 0.3 μeV for a 22/41 Å GaAs/AlAs quantum well. © 1990.
