Abstract

For one-dimensional superlattices consisting of unit cells with two films, one of which exhibits nonlinear response to the electromagnetic field, the transmissivity as a function of incident intensity and frequency is calculated for periodic and quasiperiodic structures. It is found that gap-soliton-mediated resonances for periodic structures arise from the Fabry-Pérot oscillations in the transmission band. Solitons in the stop gap are not found in the quasiperiodic case. © 1989 The American Physical Society.
