Abstract
We analyze the stability of continuous-wave (cw) solutions in the syst em of two equations with quadratic nonlinearities, describing a disper sive nonlinear optical medium. We obtain full analytical stability con ditions for the solutions. The analytical results are confirmed by sys tematic numerical simulations. The stability boundries that we obtain are necessary conditions for the formation of simultaneous dark solito ns ('simultons').
