Abstract
The main objective of this paper is to represent the analytical solutions gleaned for the propagation of the soliton pulses through a birefringent optical fiber by using Split Step Fourier Transform(SSFT). For 631.72km long fiber, the time delay of 200 and 400ps is observed between the X and Y polarization components which are generated due to birefringence properties, when the linearly polarized pulse is introduced into the non-linear fiber at an angle of 45° to the polarization axes. The Kerr non-linearity not only stabilizes the soliton spreading due to group velocity dispersion (GVD) but also maintains the level against spreading due to birefringence. The similar circumference occurs for birefringent walk-off distance. Further, it is observed that polarization components of soliton pulses move withcommon group velocity when X and Y components acquire blue and red shift respectively. This evolution scenario takes place in contrast with polarization mode dispersion (PMD) over a non-linear regime for a fiber length of 631.72 and 1264.344km with θ=30°. The results are in direct proportion to the cross phase modulation (XPM) over two polarization components.
