Reduction of dispersive waves by chirping compensation in an optical soliton source with an electroabsorption modulator

Abstract

A proper amount of group delay dispersion of a dispersion compensating fiber or a single mode fiber reduces chirping of the optical pulse generated by an electroabsorption modulator. Evaluation of the amount of dispersive wave (nonsoliton components) contained in the output of the fiber by means of the inverse scattering transform provides the condition to minimize the dispersive wave generation although it does not generally agree with the condition to minimize the pulse width.Index Terms-Eigenvalues/eigenfunctions, electrooptic materials/devices, nonlinear equations, optical communication, optical fiber dispersion, optical pulse compression, optical pulse generation.
