Transverse pattern formation in nonlinear optics was investigated in many complex arrangements both experimentally and numerically. But, as generally both nonlinearity and diffraction act simultaneously, the analytic treatment could never be performed, and moreover patterns were out of control. In this view, a rather simple system made of a thin Kerr cell and a planar feedback mirror and exhibiting
transverse effects was recently proposed.
