Phonon modes in GaAs-AIxGaI\_xAS superlattices simplify when the phonon wavevector q is perpendicular to the plane of the layers. We have studied such modes using a Raman back-scattering technique on SL's grown by MBE. The results are consistent with simple ideas of LA phonon freedom and hO phonon c

## Recent research of superlattlces and multiple quantum wells has generated considerable interest in the optical waveguiding properties of these structures for optoelectrontc applications. As a result we present a theoretical study of the index of refraction of superlattices and determine its va
