Chaos synchronization of two quantum dot light emitting diodes (QDLEDs) theoretically isstudied, which is delay coupled via a closed or open –loop and mutual coupling system. Whereas thesynchronized- chaotic systems, the dynamics of there are identical to uncoupled DLED under opticalfeedback effect. Complete synchronization was obtained under certain conditions for the couplingparameters. We evaluated the range of the QDLED’s chaos with extrinsic optical feedback in methodsof the chaos synchronization residue diagram and discussion as well of the coherence for the optimalcoupling strength range. With proper conditions of the coupling parameters and the evaluationmethods, the synchronization was satisfactorily obtained between the transmitter and receiver.

AbstractChaos synchronization of two quantum dot light-emitting diodes (QDLEDs) theoretically is studied, which are via a closed or open-loop and mutual coupling system. Whereas the synchronized-chaotic systems, the dynamics of there are identical to uncoupled dot light-emitting diodes (DLEDs) under optical feedback effect. Complete synchronization was obtained under certain conditions for the coupling parameters. We evaluated the range of the QDLED’s chaos with extrinsic optical feedback in methods of the chaos synchronization residue diagram and discussion as well as the coherence for the optimal coupling strength range. With proper conditions of the coupling parameters and the evaluation methods, the synchronization was satisfactorily obtained between the transmitter and receiver.

Chaos synchronization of delayed quantum dot light emitting diode has been studied theortetically which are coupled via the unidirectional and bidirectional. at synchronization of chaotic, The dynamics is identical with delayed optical feedback for those coupling methods. Depending on the coupling parameters and delay time the system exhibits complete synchronization, . Under proper conditions, the receiver quantum dot light emitting diode can be satisfactorily synchronized with the transmitter quantum dot light emitting diode due to the optical feedback effect.
