摘要：

The WKB approximation for the Zakharov-Shabat scattering problem is used for the analysis of decay of wave packets stimulated by a strong phase modulation in Kerr-type nonlinear medium. It is shown, that for moderate nonlinearity, solitons tend to propagate in the directions of interference fringes formed in the linear limit, and soliton parameters are reasonably well approximated with the WKB method. Simple analytical approximations for distributions of soliton parameters are reported.
