The study of nonlinear waves in layered structures proposed has become widespread, stimulated by the progress in the early 1980s. The possibility of using such waves in optoelectronic devices spurred advances in both theory and experiment. Propagation of waves in nonlinear waveguides is usually considered in passive optical systems a case of transparent, media. In this work we consider for the first time the propagation of waves in nonlinear waveguides with optical gain in the guiding film.
