''Optical soliton perturbation with full nonlinearity by trial equation method''. Optik, 157, 1366-1375.0030-40261618-1336https://www.sciencedirect.com/science/article/pii/S0030402617317473https://hdl.handle.net/11452/40175This paper studies optical soliton perturbation with spatio-temporal dispersion by trial equation method. There are five types of nonlinear fibers studied in this paper. They are quadratic-cubic law, anti-cubic law, cubic-quintic-septic law, triple-power law and log-law. Bright, dark and singular soliton solutions are recovered. In addition, singular periodic solutions naturally emerge as a byproduct of this integration mechanism.eninfo:eu-repo/semantics/closedAccessSolitonsPerturbationFull nonlinearityTrial equation methodPower-law mediumDirectional-couplersFunction schemeIntegration mechanismsKerr lawNon-linear fiberPeriodic solutionSingular soliton solutionsControl nonlinearitiesOpticsArticle0004241865001662-s2.0-8504134096313661375157https://doi.org/10.1016/j.ijleo.2017.12.113OpticsDarkness; Media Law; Periodic Solution
