Abstract

It is shown, by means of computation on a specific model, how pulse broadening in multimode gradedindex optical waveguides is significantly affected by the levels of excitation of the high-order modes. Pulse widths are computed as functions of the profile parameterα, under conditions of equal excitation, high-order mode suppression and GaAs laser excitation.
