Discrete self-trapping, soliton interactions, and beam steering in nonlinear waveguide arrays by Alejandro B. Aceves, C. De Angelis, T. Peschel, R. Muschall, Falk Lederer, Stefano Trillo, Stefan Wabnitz.
We investigate the self-trapping phenomenon in one-dimensional nonlinear waveguide arrays. discuss various approximate analytical descriptions of discrete self-trapped solutions. analyze packing, steering, and collision properties these solutions, by means a variational approach soliton perturbation theory. compare numerical results. \textcopyright{} 1996 The American Physical Society.
