An interaction of vector solitons in the frame of coupled third-order nonlinear Schrödinger equations taking into account third-order linear dispersion, nonlinear dispersion, and cross-phase modulation terms is considered. Phase nature of the solitonsʼ interaction is shown. In particular, dependence of solitonsʼ trajectories on initial distance between solitons is shown. Conditions of reflection and propagation of solitons through each other are obtained.
► Short vector solitonʼs interaction in the frame of CTNSE without SRS is studied. ► Analytical and numerical approaches are considered. ► Phase effects lead to short vector solitonʼs interaction character change.
