摘要：
We consider the propagation of stationary dark and light spatial solitons and various pairs of incoherently coupled solitons in a planar waveguide based on a thin left-handed film of a Kerr substrate. It is shown that such solitons can be formed by guided modes with positive as well as negative group velocities. The conditions in which the propagation of light and dark spatial solitons in the same waveguide is possible irrespective of the sign of the nonlinear optical coefficients of the substrate.
