The influence of the initial pulse amplitude on the stability of solitons in a highly birefringent optical fiber

In the paper the results of analysis are presented, of ultrashort pulse propagation in a highly birefringent optical fiber. For the description of soliton propagation the Coupled Nonlinear Schrodinger equations were applied, which were solved numerically using the Split-Step Fourier Method. The analysis was performed for a lossless optical fiber.
