Adaptive Isochronal Synchronization in Mutually Coupled Chaotic Systems
This paper studies the problem of isochronal synchronization of chaotic systems with time-delayed mutual coupling. Based on the invariance principle of differential equations, an adaptive feedback scheme is proposed for the stability of isochronal synchronization between two identical chaotic systems. Unlike the usual linear feedback, the variable feedback strength is automatically adapted to i...
متن کاملSynchronization of Mutually Versus Unidirectionally Coupled Chaotic Semiconductor Lasers
Synchronization dynamics of mutually coupled chaotic semiconductor lasers are investigated experimentally and compared to identical synchronization of unidirectionally coupled lasers. Mutual coupling shows high quality synchronization in a broad area of self-feedback and coupling strengths parameters phase-space. It is found to be tolerant to significant parameter mismatch which in case of unid...
متن کاملStable isochronal synchronization of mutually coupled chaotic lasers.
The dynamics of two mutually coupled chaotic diode lasers are investigated experimentally and numerically. By adding self-feedback to each laser, stable isochronal synchronization is established. This stability, which can be achieved for symmetric operation, is essential for constructing an optical public-channel cryptographic system. The experimental results on diode lasers are well described ...
متن کاملPhase synchronization in mutually coupled chaotic diode lasers.
Semiconductor lasers with optical feedback have chaotically pulsating output behavior. When two similar chaotic lasers are optically coupled, they can become synchronized in their optical fluctuations. Here we show that the synchronization is not only in the amplitude and in the timing of the pulses but that the short pulses are also phase coherent with each other. This is true even when the la...
متن کاملStability of the Controlled Synchronization Manifold in a Ring of Mutually Coupled Chaotic Systems
The active control of the unstable synchronization manifold in a shift-invariant ring of N mutually coupled chaotic oscillators is investigated. After deriving the bifurcation structures and chaotic states in the single oscillator, we find the regime of coupling parameters leading to stable and unstable synchronization phenomena in the ring, using the Master stability function approach with the...
