Abstract
We introduce a novel class of parametric optical solitons supported simulta neously by two second-order nonlinear cascading processes, second-harmonic generation and sum-frequency mixing. We obtain analytical and numerical sol utions for three-wave spatial solitons and show that the presence of an add itional cascading mechanism can change dramatically the properties and stab ility of two-wave quadratic solitary waves.
