Abstract

This paper presents an analysis of pulse propagationin nonlinear dispersive optical fiber. Whilepropagating through optical fiber, attenuation anddispersion cause amplitude decrease and temporalspread of the pulse. These linear effects aretraditionally compensated by dispersion compensatingfiber (DCF) and fiber amplifier. However, bylaunching soliton pulses it is possible to make asystem without DCF, if linear and nonlinear effectsare balanced in such way to generate stable,undistorted pulses over long distances. These pulsesof specific shape are called solitons. The existence ofsolitons in optical fibers is the result of cancellingbetween the group velocity dispersion (GVD) andself-phase modulation (SPM), both of which limit theperformance of fiber-optic communication systemswhen acting independently on optical pulsespropagating inside fibers. Soliton wave equation isgoverned by Nonlinear Schrodinger Equation(NLSE). For numerical analysis of solitonpropagation, the NLSE is solved using Split StepFourier Transform method.
