Chaos synchronization based on a continuous chaos control method in semiconductor lasers with optical feedback.
Chaos synchronization using a continuous chaos control method was studied in two identical chaotic laser systems consisting of semiconductor lasers and optical feedback from an external mirror. Numerical calculations for rate equations indicate that the stability of chaos synchronization depends significantly on the external mirror position. We performed a linear stability analysis for the rate...
متن کاملChaos Synchronization in Semiconductor Lasers With Optoelectronic Feedback
Chaos synchronization is experimentally investigated in semiconductor lasers with delayed optoelectronic feedback. Depending on the coupling strength of the driving signal to the receiver, the lasers fall into different regimes of chaos synchronization or modulation. Synchronization happens when the coupling strength to the receiver matches the feedback strength to the transmitter, where the re...
متن کاملChaos Synchronization and Chaotic Signal Masking in Semiconductor Lasers With Optical Feedback
Theoretical and experimental investigations of chaos synchronization and its application to chaotic data transmissions in semiconductor lasers with optical feedback are presented. Two schemes of chaos synchronization—complete and generalized synchronization—are discussed in the delay differential systems. The conditions for chaos synchronization in the systems and the robustness for the paramet...
متن کاملSemiconductor Lasers: Stability, Instability and Chaos
Lasers are essentially chaotic system. However, semiconductor lasers are classified into stable class B lasers. Meanwhile, they are easily destabilized by external perturbations (introduction of extra degree of freedom). We discuss chaos in lasers and also instability and chaos in semiconductor lasers. Recently, new semiconductor lasers with extra device structures have been developed and they ...
متن کاملThe nonlinear Gain and the Onset of Chaos in a Semiconductor Laser with Optical Feedback
The effect of the inclusion of nonlinear gain saturation in the governing equations of a semiconductor laser with optical feedback is numerically analyzed. The dependence of the route to chaos on the intensity of the nonlinear term and on the form of gain saturation, are considered. It is found that the inclusion of gain saturation causes significant changes in the behavior of the laser with re...
