The Nonlinear Schrödinger Equation
The nonlinear Schrödinger equation (NSE) is of particular importance in the description of nonlinear effects in optical fibers. It is named after the similarity that it shows to the well known equation derived by Erwin Schrödinger. This equation is one of the basics of quantum theory and describes the behavior of a particle in an arbitrary potential. Contrary to that, the NSE is based on the classical Maxwell Theory and it describes the behavior of wave packets in a nonlinear environment. But, as can be seen from the soliton section, these classical wave packets behave — under particular circumstances — like particles as well.
