Abstract

New results for propagation losses, 4.7dB/cm, in (Al, Ga)As multiple quantum well (MQW) waveguides subjected to impurity induced disordering (IID) are described. Substantial, up to 90meV, blue shifts in the absorption edge imply the suitability of this IID process for optoelectronic integration applications.
