A recent experiment showed that optical pattern-forming systems with strong nonlinear effect can be designed based on large-scale arrays of optoelectronic feedback circuits. Using various synthetic nonlinearities and controllable spatial coupling, a variety of transversal optical patterns were observed in the system. The results of a theoretical study performed on such a spatially distributed nonlinear optical model are presented. The existence of web patterns in the system with cosine nonlinearity is shown. The new spatial structure emerges from clusters of localized states through a sequence of spatial bifurcations on increasing the control parameter of the system. The results are in good agreement with experimental observation.
