Chaotic dynamics of a semiconductor laser with double cavity feedback: Applications to phase shift keying modulation

Controlling the unstable emission of a semiconductor laser subject to conventional optical feedback with a filtered feedback branch

“…5 where the CW stable region decreases, while more chaotic regions appear, as the filter width λ is increased. In fact, we have recently shown that CFB systems exhibit strong chaos for increasing feedback strength in one cavity [13]. It is worth mentioning that if the filter width is too narrow and it is not well tuned at the Hopf frequency, the FFB is inefficient.…”

Theoretical analysis of semiconductor ring lasers with short and long time-delayed optoelectronic and incoherent feedback

“…From the point of view of applications the dynamics of delay systems is gaining more and more interest [6]. While initially it was considered more as a nuisance, it is now viewed as a resource that can be beneficially exploited for chaos based communications [7][8][9], random bit generation [10] and information processing [11,12].…”

“…With the success of chaotic synchronization such systems have become prime candidates for chaotic communications [15]. A number of experiments have demonstrated the possibility of encoding, transmitting, and decoding information by forcing the receiver to synchronize to the chaotic carrier of the transmitter [7][8][9]. The primary requirement to achieve such synchronization appears to be that the transmitter and receiver systems be closely matched.…”

Nonlinear dynamics and chaos synchronization in Mackey-Glass electronic circuits with multiple time-delayed feedback

“…Recently, several studies have investigated the dynamics of systems with more than one time-delayed feedback loop with the aim of controlling and stabilizing chaos [21][22][23][24]. Nonlinear dynamics and chaos synchronization in dynamical systems with multiple time-delayed feedback has been reported for logistic maps [25], prey-predator systems [26], and coupled semiconductor laser systems [27][28][29][30][31]. It is important to understand chaos synchronization in coupled nonlinear dynamical systems with multiple time delays, especially the synchronization mechanism in neuronal networks and biological systems.…”
