GONZALEZ-GAXIOLA, O.; BISWAS, A.; KAMIS ALZAHRANI, A.  e  BELIC, M. R.. Optical soliton perturbation with spatio-temporal dispersion having Kerr law nonlinearity by the variational iteration method. Rev. mex. fis. [online]. 2020, vol.66, n.4, pp.404-410.  Epub 31-Jan-2022. ISSN 0035-001X.  https://doi.org/10.31349/revmexfis.66.404.

This paper studies optical soliton perturbation that appears with Kerr law nonlinearity having spatio-temporal dispersion. The numerical scheme adopted is the variational iteration method. The perturbation terms are of Hamiltonian type and stem from inter-modal dispersion, self-steepening and nonlinear dispersion. Both bright and dark solitons are taken into consideration.

Palavras-chave : Nonlinear Schrödinger equation; Kerr law nonlinearity; variational iteration method; optical solitons solutions; perturbation.
