Abstract
The propagation of spatial soliton arrays in waveguides with nonlinear boundaries was studied theoretically. We found equilibrium states of the soliton arrays in a waveguide by employing soliton perturbation theory. The propagation of the array was shown to be accompanied by oscillations of the solitons’ positions and phases. The oscillation modes of the system were analyzed analytically and numerically, revealing the presence also of nonmechanical oscillations associated with the soliton phases.
