Abstract: We report the formation of spatial structures induced by a spatial offset in a two-dimensional nonlinear optical interferometer in which diffractive effects are absent. The observed patterns arise from the destabilization of wide, continuous bands in the Fourier spectrum. The selection of these bands is shown to be determined by the interplay between the amount of spatial offset and the strength of the diffusion in the nonlinear optical material.
