Abstract

The possibility of the formation of spatial-temporal solitons (optical bullets) in coupled quadratically nonlinear gradient waveguides in the range of normal dispersion of the group velocity is investigated. The generation of optical bullets by as well an initial Gaussian beam is demonstrated at both frequencies and only at the fundamental frequency.
