Nonlinear cone optical fiber- propagation characteristic.

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 mode theory is used. propagation of pulse, in the cylindrical nonlinear segment, is analyzed using spli-step. Fourier method. Some results of computation for the selected cone conlinear optical fibers are also presented.
