Abstract

Based on the three-energy level exciton model of the quantum dot lasers (QDLs), the nonlinear dynamics of the sole ground-state emitting QDL (GS-QDL) under external optical injection is numerically studied. The results show that the GS-QDL can generate period-one, period-two, multi-period, chaotic pulse and injection locking states under suitable injection parameters. By analyzing the distribution of these dynamic states in the injection parameter space, it is found that the period-one state and injection locking state occupy a large area, but the region of the complex dynamics is relatively small. Moreover, the complexity of the chaotic signals generated by the GS-QDL is quantified by the permutation entropy calculation. The results show that the complexity of the chaotic signals is less than 0.90, which indicates that the GS-QDL is low sensitivity to external optical injection. The GS-QDL can be used in isolator-free photonic integrated circuits.
