Abstract:
Regimes of motionless and moving switching waves and discrete solitons are found for a two-dimensional set of weakly coupled single-mode optical fibers. A regime of a stable sharply localized soliton structure whose center of gravity moves along a curvilinear closed trajectory in the cross section is found. Scenarios of the regime destabilization upon variation of system parameters are considered.
