We analyze various scenarios of the dynamics of a spatial soliton interacting with a sharp potential barrier (SPB) in the complex Ginzburg–Landau model with the cubic-quintic nonlinearity. In optical realizations of the model, the SPB corresponds to a local notch in the refractive-index field. Possible outcomes of the interaction include splitting of the soliton, its lateral drift, formation of tree-like multi-jet patterns, and destruction of the soliton. The results suggest applications to the design of two- and multi-route splitters of light beams.
