Abstract
A comprehensive bifurcation analysis of Quantum-Dot (QD) spin-polarized vertical-cavity surface-emitting lasers (VCSELs) subject to optical feedback is demonstrated in the paper. Based on modified spin-flip (SFM) equations, we adopt the fourth-order Runge-Kutta algorithm for simulating numerically to study the nonlinear behaviors. The bifurcation diagrams with optical feedback coefficient and optical feedback delay time are plotted to observe the different dynamic behaviors and the route to chaos. Finally, we compare the different nonlinear states found in the bifurcation diagram in the time series, power spectra, and phase portraits to observe the distinction of chaos and non-chaos.
