“…In these reported results, one can see that both theoretical model and experimental studies are intensively presented to observe the rich nonlinear behaviors including the periodic, quasi-periodic, and chaotic phenomena by judiciously adjusting the strengths of external injections and/or optical feedbacks. The achieved dynamical results are widely used to perform the photonic microwave signals [8,9], secure optical communications [10], optical switching [11], radar [12], all-optical AM-to-FM conversion [13], and radio-over-fiber links [14]. Generally, the conventional quantum well laser has a large line width enhancement factor that results in the large chaotic region with the change of external injection or feedback level [15].…”

In this study, the research on the nonlinear dynamics of semiconductor quantum dot laser with two time-delayed optical feedbacks is numerically investigated. Results show that the nonlinear dynamics behaviors of the laser are very sensitive to the rich system parameters in which both feedback strength and bias current are easily controlled to significantly influence the nonlinear dynamics including the periodic state and chaotic state. By judiciously adjusting the bias current of the laser or the feedback strength in the external cavity, period one, period doubling, quasi-period, and chaos are achieved. The feedback levelrelated bifurcation diagrams are analyzed in detail while fixing another feedback level at a constant or varying the bias current. In addition, the translation variables of the 0-1 test method that are clearly bounded for regular behavior and exhibit the Brownian motion for irregular phenomenon are adopted to further evaluate the periodic state and the chaotic state. These results can give insight into the quantum dot laser-based applications in various optical technologies.
