Abstract

Recent experimental studies^1,2 have shown that in coupled quantum wells (QWs) the electrooptical properties can be significantly modified and enhanced compared with single QWs. The device applications of QWs rely on field-induced changes in strong excitonic transitions between confined levels (quantum confined Stark effect). To predict the performance of the potential device and interpret correctly the experimental results, it is necessary to estimate changes in both resonant energies and oscillator strengths of these transitions. Therefore, the choice of the right model, adequately taking into account all the interactions occurring in the QW system, is important.
