have performed a semi-empirical calculation of the refractive index changes induced by a
perpendicular electric field in quantum wells. This calculation is based on experimental
electroabsorption data, together with absorption sum rules that have recently been
developed. They find good agreement with published experimental results. These results are
important to the development of electro-optic and high-speed electroabsorption quantum
