Study of soliton propagation inside optical fiber for ultra-short pulse

Abstract

We will study the pulse propagation in optical fiber. The effect of non-linearity and dispersion of the pulse propagation causes temporal spreading of pulse and it can be compensated by nonlinear effect. When the effects are combined they can generate stable, undistorted pulses called soliton over long distances. Numerical analysis can be carried out using different types of method including Fourier series analysis techique, Split Step Fourier Method. An extensive study has been carried out to find the appropriate analysis method. Different types of pulse was used including Hyoperbolic secant, Gaussian and Super-Gaussain pulses.
