Notes:
We present an approach to the investigation of structural disorder in quantum wells (QWs) based on the reflectivity line shape analysis of radiatively coupled QWs. In the case of anti-Bragg structures, as a consequence of the condition of destructive interference, the reflectivity spectrum is indeed extremely sensitive to vertical disorder. We exploit the method in the case of GaAs/AlGaAs structures and we demonstrate the possibility of measuring differences in the excitonic transition energies of the two QWs as small as 10% of the inhomogeneous broadening. © 1999 American Institute of Physics.
