Experimental synchronization of spatiotemporal disorder.
We report experimental evidence of a time-lag synchronization of spatiotemporal complexity. The experiments were performed on two unidirectionally coupled, nonlinear-optical systems of single-feedback type. Synchronization was investigated for different degrees of complexity of the spontaneous structures, which were analyzed with cross-correlation functions and mutual information. Numerical simulations yield comparable results and throw a light on the impeding role of spatial inhomogeneities.
