Abstract

Most optical studies in quantum wells have dealt with rectangular structures where an a ~100-Ǻ GaAs layer is sandwiched between ~100- Ǻ AlGaAs barriers. In contrast, we present a novel coupled-quantum-well (CQW) structure in which the ~100- Ǻ GaAs is replaced by two narrow GaAs wells (46 Ǻ) coupled by a thin AlGaAs barrier (11.5 Ǻ) between them.
