Numerical analysis of nonlinear soliton propagation phenomena usingthe fuzzy mesh analysis technique

摘要

A novel numerical technique, the fuzzy mesh analysis technique, isndeveloped to study the nonlinear propagation phenomena of solitons in annoptical fiber. The main advantage of this technique is the variation ofnmesh size with the shape of soliton pulses along the propagationndistance such that: 1) the calculation efficiency can be enhanced and 2)nthe number of sampling points can be greatly reduced. It is shown thatnthe fuzzy mesh analysis technique is capable of analyzing thenpropagation phenomena of high-power solitons, pulse compression, andnsoliton interaction in an efficient manner
