摘要: Simultaneous solitary wave solutions for laser propagation in nonlinear parametric media with up to (3 + 1) dimensions are proved exist. The combination of the large dispersion a Bragg grating and strong nonlinearity chi((2)) optical material results stable behavior short interaction distances low power requirements. obtained by using effective mass approximation reduce coupled equations those describing dispersive waveguide, verified solving complete set band-gap numerically.
