Polarized solitons in a cubic-quintic medium

The interaction of both scalar and counter-rotating polarized steady state pulses (SSP) is studied numerically for a medium characterized by nonlinear susceptibilities of the third and the fifth order (a cubic-quintic medium with,$\chi_{3}>0,\chi_{5}<0$). The collision of two plateau-shaped solitons proved to be essentially inelastic, as a number of secondary elliptically polarized solitary waves arise as a result of interaction of steady-state pulses.
