摘要：

The existence of localized and resonant optical waves associated with the surface of a semi-infinite superlattice or ifs interface with a substrate is reported, considering the case of s-polarization (transverse electric modes). These modes appear as well defined peaks of the density of states, either inside the minigaps or inside the bulk bands of the superlattice. The density of states, function of the frequency omega, and the wave vector k(parallel to) (parallel to the interface), are obtained from an analytic determination of the response function for a semi-infinite superlattice with or without a cap layer.
