摘要：

We outline a continuum model of optical modes in GaAs/AlAs superlattices with particular emphasis on the modes vibrating in the AlAs restrahl band. Results are given for the AlAs modes of [100] and [111] superlattices and are shown to give excellent agreement with a microscopic model. We also demonstrate the effect of using the mass approximation on the dispersion of the superlattice modes.
