Abstract

This paper presents an analysis of pulse propagation
in nonlinear dispersive optical fiber. While
propagating through optical fiber, attenuation and
dispersion cause amplitude decrease and temporal
spread of the pulse. These linear effects are
traditionally compensated by dispersion compensating
fiber (DCF) and fiber amplifier. However, by
launching soliton pulses it is possible to make a
system without DCF, if linear and nonlinear effects
are balanced in such way to generate stable,
undistorted pulses over long distances. These pulses
of specific shape are called solitons. The existence of
solitons in optical fibers is the result of cancelling
between the group velocity dispersion (GVD) and
self-phase modulation (SPM), both of which limit the
performance of fiber-optic communication systems
when acting independently on optical pulses
propagating inside fibers. Soliton wave equation is
governed by Nonlinear Schrodinger Equation
(NLSE). For numerical analysis of soliton
propagation, the NLSE is solved using Split Step
Fourier Transform method.
