Modeling of synchronization in quantum dot semiconductor lasers

Chaos synchronization between two quantum dot (QD) semiconductor lasers with optical feedback and optical injection is modeled by the rate equations model including wetting layer, ground state and excited state. Three systems are discussed: open-loop, closed-loop and mutual-coupling. For each case, both generalized and complete synchronization are discussed. Additionally, optically injected QD laser systems are also discussed. Two QD lasers with the same and different parameters are used. Best synchronization is obtained for the cases of open-loop and injected systems. Electron and hole occupations in the QD ground and excited states are contributes in the chaotic behavior.
