Optical Pulse Compression in Fibre

Abstract

Optical pulse compression using similariton propagation in an optical fibre with decreasing dispersion has been demonstrated for the first time. This compression scheme is a practical application of the sech-similariton solution to the generalized nonlinear schrodinger equation(NLSE) with distributed coefficients recently found using the self similarity technique. The fibre with a decreasing dispersion profile is constructed using the comb-profile approximation technique and different variations of the technique have been developed to improve the accuracy of the approximation.
