Abstract

Numerical analysis of the nonlinear cone optical fiber using the coupled mode theory and the split-step Fourier method is described. The nonlinear cone optical fiber is divided into a large number of appropriate cylindrical segments. In the analysis of light propagation between two segments of various diameters, the coupled mode theory is used. Propagation of a pulse, in the cylindrical nonlinear segment, is analyzed using the split-step Fourier method. Some results of computation for the selected cone conlinear optical fibers are also presented.
