It is essential to pixellate arrays of optically bistable switching elements in order to remove cross-talk caused by diffusion. We solve for the problem of cylindrical pixel nonlinear Fabry-Perot cavities, illuminated by nonuniform radiation beams, accounting for carrier diffusion and surface recombination. It is found that the additional carrier sink produced by the transverse surface is not detrimental to the switching power if the pixel area is small enough or if the surface recombination velocity is low enough.
