Abstract

The trapping of weak guided modes by a strip waveguide induced by a strong spatial soliton in a planar waveguide based on a thin left-handed film with a right-handed linear cover and a substrate with the Kerr effect at a frequency near the zero group velocity of the TE mode is considered. It is shown that a bright (dark) soliton can induce a strip waveguide not only for a positive (negative) nonlinear optical coefficient of the substrate, but also for a negative (positive) one, which is due to the existence in the original planar waveguide of guided modes with both positive and negative group velocities.
