The dispersion of the propagation constants of TE2-modes in a thin left-handed film on a substrate with the Kerr effect has been considered in a narrow frequency range near the zero of a group velocity of the mode. It is shown that such dispersion can be controlled by varying the intensity of the light field with a change in frequency. The conditions, under which the propagation constants remain constant when the frequency changes, have been determined. Soliton-like wave packets have been considered.
