Abstract

Changes of index of refraction of semiconductor superlattices due to electric field are studied theoretically. A parabolic band effective-mass approximation is used for the conduction, heavy-hole, and light-hole bands. Excitonic effects are considered for wide barrier superlattices (or multiple quantum wells) and are found to substantially enhance the electro-optic effect near the onset of the excitonic absorption.
