Domain coexistence in nonlinear optical pattern formation.

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