Abstract

We study the evolutions of spatiotemporal chaos for the photorefractive ring oscillator. As the system parameters are changed, we obtain different patterns such as the frozen random state, the pattern selection state, the defect chaotic diffusion state and fully developed turbulence state in the one- dimensional map lattice system. We can observe symmetry breaking from four corners and the boundaries and finally lead to spatiotemporal chaos in the two-dimensional map lattices system. Then we demonstrate that the global and local constant bias can suppress spatiotemporal chaos in photorefractive ring oscillator by varying the bias strength. Only if we choose suitable bias strength, spatiotemporal chaos in photorefractive ring oscillator system can be controlled into stable periodic states.
