Abstract
We report the first studies of exciton luminescence spectra from asymm etric double quantum wells (DQWs) of very similar width. The DQWs were of GaAs/AlGaAs and the differences in widths of the coupled wells wer e one or two monolayers. The coupled direct and indirect exciton state s anticross with a resonance splitting of 1.33 meV. An additional lumi nescence line appearing at low temperatures is identified as a localiz ed indirect exciton. (C) 1997 American Institute of Physics.
