Abstract

In recent times important attention hits been given to nonlinear solitary waves, solitons, which hold great promise in the creation of devices for the formation and control of supershort radioimpulses. However, even in the presence of a suitable nonlinearity and dispersion, only some materials may used for the formation of solitons, in the main through small length or transverse instabilities. A promising material in this context may be fibers, which, with their large length and small absorption, exhibit important nonlinear effects even for low powered laser pumping (smaller than the self-focussing threshold). In fiber where electromagnetic solitons arc excited, the system is described by the solution of the nonlinear Schrödinger equation.
