Abstract

Multiple cations intermixed In_0.53Ga_0.47As/In_0.52Al_0.48As quantum well structure with 60 angstroms well width is investigated by using the expanded form of Fick's second law. It was found that a maximum compressive strain of 0.64% is obtained when annealing time reaches 3 hours at 812 degree(s)C in the indium sublattice. For a small interdiffusion, i.e. 1 to 1.5 hrs, the subband separation between the lowest heavy and light hole states is at its greatest. This is a major contribution to the band structure and averaged density of states, thus enhancement in optical gain up to 40% is obtained. For a large interdiffusion, i.e. up to 6 hrs, a large blue shift of the peak gain from 0.842 to 1.016 eV is observed.
