### Nonlinear Schrödinger Equation | IntechOpen

The equation can be solved by introducing the Green function in the time domain, and it is used as the tool for the estimations of high-order dispersion and nonlinear coefficients. For the conventional fibers, SMF, NZDSF, and DCF, the higher-order nonlinear effect contribution to β 4 can be neglected. This can be deduced that each effect has less impact for another coefficient’s estimation. The Green function can also be used for the solving of 3 + 1 dimension NLSE. We consider the nonlinear Schrödinger equation (NLS) (see below) with a general “potential” F(u), for which there are in general no conservation laws. The main assumption on F(u) is a growth rate... 5. Conclusion. In this study, the soliton solutions to the higher order nonlinear Schrödinger equation have been extracted.
