Combined optical solitons with parabolic law nonlinearity and spatio-temporal dispersion

Abstract

AbstractIn this work, combined optical solitons are constructed in a weakly nonlocal nonlinear medium. The spatio-temporal dispersion (STD), parabolic law nonlinearity, detuning, nonlinear dispersion as well as inter-modal dispersion are taken into account. The integration tool that is applied is the complex envelope function ansatz. The influences of different parameters on dynamical behavior of combined optical solitons are discussed. The results are useful in describing the propagation of combined optical solitons with STD and parabolic law nonlinearity.Keywords: combined solitonsnonlocal nonlinear Schrödinger equationparabolic law nonlinearityspatio-temporal dispersionweakly nonlocal nonlinearityPACS numbers: 05.45.Yv42.65.Tg42.81.Dp Additional informationFundingFunding.
