Abstract: The propagation of light beams in a nonlinear cubic medium with the refractive index periodically modulated along one transverse coordinate is considered. The profiles of soliton beams are found and their stability is studied. It is shown that the refractive-index modulation causes the collapse suppression and soliton stabilisation almost within the entire region of their existence.
