Abstract

Quantum well intermixing has become a powerful tool in monolithic integration of semiconductor lasers, low loss waveguides, phase modulators, etc. The electronic structure of the intermixed samples is, however, still poorly understood. In particular, the behaviour of upper subband levels upon intermixing deserves more study, both from the viewpoint of interest in its fundamental physics and from its potential technological applications, such as devices based on χ² effect or electro-refraction effects, etc.
