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