We investigate dynamics of a wave packet formed by tunnel-coupled forward and backward waves in a waveguide structure composed of materials with different in sign indices of refraction. Expressions for the wave packet duration and maximum group velocity are obtained taking into account second order dispersion, cubic nonlinearity and nonlinear dispersion. The possibility to control the velocity of forward wave by means of an external magnetic field is discussed.
