Propagation phenomena of nonlinear film guided waves in a configuration with material losses: a numerical analysis.
The propagation of TE-polarized nonlinear guided waves excited at different points of the nonlinear dispersion curve has been examined along a thin film bounded by two identical self-focusing media with linear absorption. The evolution of the fields indicates that the stable branches of the nonlinear dispersion curve can be passed through when the total energy flow decreases because of absorption. The evolution of nonstationary waves initially excited at unstable branches of the dispersion curve shows significant dependence on the magnitude of the absorption.
