Discrete self-trapping, soliton interactions, and beam steering in nonlinear waveguide arrays

Abstract

We investigate the self-trapping phenomenon in one-dimensional nonlinear waveguide arrays. We discuss various approximate analytical descriptions of the discrete self-trapped solutions. We analyze the packing, steering, and collision properties of these solutions, by means of a variational approach and soliton perturbation theory. We compare the analytical and numerical results. \textcopyright{} 1996 The American Physical Society.
