In the study of coupled chaotic oscillators, investigation of transition of the attractor's region is important problem to clarify spatiotemporal chaos. We observe self-switching phenomena in chaotic oscillators coupled by one resistor. In our system, synchronization of self-switching phenomena is observed for the rst time. The term \synchronization of self-switching phenomena" means that the a...

This paper investigates the synchronization of two Newton-Leipnik Chaotic Systems. A new sufficient condition of global asymptotic synchronization is attained from the theory of stability of time-varying systems. In addition , compared with the previously proposed method , the sufficient condition for the synchronization of two linearly coupled unified chaotic systems is simpler and less conser...

The study of chaos can be introduced in several applications as: medical field, fractal theory, electrical circuits and secure communication, essentially based on synchronization techniques. The synchronization for chaotic systems has been extended to the scope, such as generalized synchronization, phase synchronization, lag synchronization, and even anti-synchronization (Pecora & Carroll, 1990...

Chaotic lag synchronization is a subtle dynamical phenomenon in which the states of two mutually coupled, nonidentical chaotic oscillators follow each other with a fixed time delay. We investigate to what extent lag synchronization can be observed in laboratory experiments. Our measurements indicate that due to the influence of noise, lag synchronization appears to occur intermittently in time....

A communication scheme based on the synchronization of two chaotic semiconductor lasers is experimentally tested. The Chaos in the single-mode semiconductor lasers is generated by means of an optoelectronic feedback. Synchronization of the chaos is achieved by coupling a fraction of the transmitter’s output power into the driving current of the receiver. We present experimental results on the r...

We demonstrate experimental chaos synchronization between two chaotic semiconductor lasers subjected to polarization-rotated optical feedback and unidirectional injection. This system allows high-quality synchronization to be obtained between dissimilar lasers in a wide range of chaotic operating regimes. Another feature of this system is its operation at high characteristic frequencies, taking...

Synchronization phenomena in complex systems are important to describe various higher-dimensional nonlinear phenomena in the field of natural science. Studies on synchronization phenomena of coupled oscillators are extensively carried out in various fields; physics, biology, engineering and so on [1][4]. Because many researchers suggest that synchronization phenomena of coupled oscillators have...

This work combines the Theory of Chaotic Synchronization with the Theory of Information in order to introduce the chaotic channel, an active media formed by connected chaotic systems. This subset of a large chaotic net represents the path along which information flows. We show that the possible amount of information exchange between the transmitter, where information enters the net, and the rec...

This study constructs a novel four-dimensional fractional-order chaotic system. It verifies chaotic nonlinear dynamic behaviors and physical reliability by numerical simulation and hardware circuit design. For a class of parameter uncertainty fractional different-lags ( i ) chaotic systems, the authors design a time-delayed ( ) synchronization controllers and parameter adaptive laws. It proves ...

Synchronization in chaotic systems has become an active area of research since the pioneering work of Pecora and Carroll. Most existing works, however, rely on a passive approach: A coupling between chaotic systems is necessary for their mutual synchronization. We describe here a feedback approach for synchronizing chaotic systems that is applicable in high dimensions. We show how two chaotic s...
