Simulation of an External Cavity Nanostructure Quantum Dot Semiconductor lasers dynamics with Optical Feedback

Stability of an Long External Cavity (LEC) of Quantum Dot Semiconductor lasers(QDSEL) dynamics with Optical Feedback is studied. The effect of long external cavity length and linewidth enhancement factor of Quantum Dot Semiconductor lasers(QDSEL) are studied. The rate equations describing QDSEL dynamics are solved numerically. The simulation shows that the photon density are sensitive to long external cavity length. The study proves that QDSEL dynamics is strongly affected of long External cavity length and linewidth enhancement factor with optical feedback in chaos communication lasers
