Domain coexistence in nonlinear optical pattern formation - art. no. 026207

We report on domain coexistence of a variety of different modes in a two-di mensional nonlinear optoelectronic model. The changes of stabilities of the se modes are shown to give rise to new forms of spatial and spatiotemporal structures. The existence of these domain patterns explains some of the pat terns recently observed in an optical system with a large array optoelectro nic feedback circuit.
