Chaos synchronization in quantum dot semiconductor lasers with negative optoelectronic feedback

Chaos synchronization is investigated in quantum dot semiconductor lasers with negative optoelectronic feedback. Depending on the coupling strength between transmitter and receiver quantum dot semiconductor Laser. Synchronization happens when the coupling strength to the receiver matches the feedback strength to the transmitter, where the receiver output reproduces the output of the transmitter regardless of the presence of channel distortion or an encoded message. when feedback strength of transmitter, receiver quantum dot semiconductor Laser and coupling feedback strength are equal (−0.3), time delay of transmitter, receiver quantum dot semiconductor Laser and coupling are sensitive to synchronization.
