“…Therefore, by generating different wide band gaps, the absorption and emission wavelengths of QD are tunable. So, the property of scale-dependent emission wavelength for QD is widely applied in various technologies such as optical display [27], laser amplification [28], emission [29], and photodetector [30]. Therefore, the feature of strong carrier confinement in semiconductor QD structure will play a very important role in laser device.…”

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.
