Abstract
The quantum-confined Stark effect and the influence of magnetic confinement on the optical absorption spectra for a highly excited quantum-well wire are analyzed. The shifts of the exciton resonance and the changes of its oscillator strength are evaluated. The calculated spectra of magnetoabsorption and of magnetoluminescence for a modulation-doped quantum wire both agree qualitatively with corresponding recent measurements.Keywords
