Abstract
It is shown that the dispersion of nonlinearity in waveguide structures admitting strong linear coupling between two unidirectional waves significantly affects the dynamics of the wave packet propagation. In a nonamplifying medium, there is a principal possibility (not inherent in one-wave structures) that an envelope shock wave would form on the leading front of the wave packet.
