Abstract
In this paper we present a study of the electroreflectance spectra of several quantum wells. Using polarized light we are able to separate the contributions related to the linear electro-optical tensor (Pockels effect) and the quadratic electro-optical tensor (Kerr effect). We have observed an enhancement of the linear electro-optical contribution to the electroreflectance spectra in the light-hole region of the fundamental transition. Such enhancement is not observed in the fundamental transition of the III-V compounds and is due to the mixing of the atomiclike orbitals induced in a quantum well.
