We theoretically study chaos synchronization of two diodes that emit light using quantum dots (QDLED) which are delay coupled via a closed and open –loop coupling system active relay. While the chaotic systems are synchronized, their dynamics is identical to a single QDLED with delayed optoelectronic feedback for an open –loop system active relay. There is total synchronization in the system depending on the coupling parameters., i.e., the extent of the QDLED’s chaos regime under external optoelectronic feedback is evaluated in terms of the chaos synchronization residue and lag diagram for the optimal coupling strength range is debated as well. Under apposite conditions, the headset QDLED can be satisfactorily harmonized with the transmitter QDLED due to the optoelectronic feedback effect.
