Using the extended spin-flip model, we theoretically investigate the polarization switching dynamics of a vertical-cavity surface-emitting laser subject to negative optoelectronic feedback. The results show that when the laser operates at two different the spin-flip rates, the feedback intensity and delay time have great influence on polarization switching dynamics. At a slow spin-flip rate, with the increase of feedback intensity, switching current increases linearly, that the X polarization mode is compressed is contrary to the reported results based on isotropic optical feedback. The reason may be due to the fact that the negative optoelectronic feedback improves the X polarization mode threshold; the effect of delay time will vary with feedback intensity. At a fast spin-flip rate, the effect of feedback strength is different from at a slow spin-flip rate, the switching point current undergoes a process in which the current increases first and then decreases gradually, the switching point current is more sensitively dependent on the feedback strength; while effect of the delay time is similar to that at a slow spin-flip rate. In addition, we find that the spontaneous emission noise has a great influence on polarization switching dynamics.

Based on the spin-flip model, the characteristics of multiple polarization switching (PS) in mutually-coupled vertical-cavity surface emitting laser (VCSEL) are investigated by continuously changing some important parameters. The simulated results show that multiple PS can be generated through continuously varying the mutually-coupled strength, the oscillation frequency of one VCSEL or the oscillation frequencies of two VCSELs. The characteristics of multiple PS under the above three scenarios are analyzed, and the influence of the delay-coupled time on the performance of multiple PS is also discussed.
