The perturbation terms are from inter-modal dispersion and self-steepening effect that is considered with maximum allowable intensity. The parameter constraints that naturally emerged from the integration scheme are enumerated.330-337 PagesenAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/ConcatenationSelf-steepeningSelf-frequency shiftArticle
