Spatiotemporal Communication with Synchronized Optical Chaos

Optical textures: characterizing spatiotemporal chaos.

Macroscopic systems subjected to injection and dissipation of energy can exhibit complex spatiotemporal behaviors as result of dissipative self-organization. Here, we report a one- and two-dimensional pattern forming setup, which exhibits a transition from stationary patterns to spatiotemporal chaotic textures, based on a nematic liquid crystal layer with spatially modulated input beam and opti...

Influences of the Driving Sequence to Synchronized Spatiotemporal Chaos

In the driving synchronization of two one-way coupled map lattices (OCML) spatiotemporally chaotic systems, the driving sequence plays a very important role. In this paper, we investigate some of its influences to the chaotic system. First, we study the OCML system driven by a periodic sequence. The resulting lattice sequences are also periodic, with the same period as the driving sequence is. ...

Synchronicity from Synchronized Chaos

The dynamical systems paradigm of synchronized chaos may realize the philosophical notion of “synchronicity”. Effectively unpredictable chaotic systems commonly exhibit a predictable relationship when they are coupled through only a few of many variables, a relationship that can be highly intermittent in realistic configurations, as with philosophical “synchronicities”. Synchronicities are mean...

Images of synchronized chaos: Experiments with circuits.

Synchronization of oscillations underlies organized dynamical behavior of many physical, biological and other systems. Recent studies of the dynamics of coupled systems with complex behavior indicate that synchronization can occur not only in case of periodic oscillations, but also in regimes of chaotic oscillations. Using experimental observations of chaotic oscillations in coupled nonlinear c...
