Abstract:
The evolution of the complex envelope of a family of single and pair pulses having the form of truncated elliptic cosines сп(т, к) with different к values 0 < к ^ 1, including pulses corresponding to solitons (for which к = 1), has been studied by means of a numerical solution of the nonlinear Shcroedinger equation describing the propagation of an intensive localized wave field in a waveguide with cubic polarization characteristics. Analysis of the nonlinear interaction of pair pulses enables one to estimate the limiting transmission rates of digital signals and to work out recommendations for selection of the optimal pulse form.
