Abstract

An error function is used to model the compositional profile in an undoped InGaAs/GaAs single quantum well after disordering. Calculation of the subband structure, interband transition energies, overlapping wavefunction and polarization dependent interband absorption coefficient are presented for various stages of disordering. It is shown that the combined effects of strain and disordering in quantum well structures can be used to tailor the absorption edge.
