The interaction of spatial soliton pairs with a nonlinear interface was studied theoretically. With mediation of the interface, the two solitons exhibited efficient switching and double switching. A closed-form particlelike model, validated by propagation calculations, yielded the soliton trajectories and switching characteristics.
