ALVARADO-MENDEZ, E. et al. Quasi-surfaces waves under drift and diffusion mechanism in nonlinear interfaces. Rev. mex. fis. [online]. 2004, vol.50, n.5, pp.478-483. ISSN 0035-001X.

We study numerically and theoretically the behaviour of one-dimensional bright spatial soliton in an interface formed by a nonlinear media under drift and diffusion nonlinearities, and a linear one in the second media. The mechanism of diffusion causes self-bending effect on the soliton, and in consequence it is launched to nonlinear interface; after that the soliton is reflected to nonlinear medium and self-bending by diffusion newly launched the soliton to the interface. In consequence, a quasi-surface wave is formed. We present details about the trajectory, coefficient of saturation and energy during the dynamics of the spatial soliton.

Keywords : Nonlinear waveguides; optical solitons; photorefractive surface waves.
