REDUCTION OF DISPERSIVE WAVES BY CHIRPING COMPENSATION IN AN OPTICAL SOLITON SOURCE WITH AN ELECTROABSORPTION MODULATOR

A proper amount of group delay dispersion of a dispersion compensating fiber or a single mode fiber reduces chirping of the optical pulse ge nerated by an electroabsorption modulator, Evaluation of the amount of dispersive wave (nonsoliton components) contained in the output of th e fiber by means of the inverse scattering transform provides the cond ition to minimize the dispersive wave generation although it does not generally agree with the condition to minimize the pulse width.
