Based on the Spin-flip Model (SFM), we numerically investigated the polarization switching dynamics of 1550 nm Vertical-cavity Surface-emitting Lasers (VCSELs) subjected to Negative Optoelectronic Feedback (NOEF). The results show that the multiple polarization switching points are shifted to lower injection currents with increasing the optoelectronic feedback strength. With further increase of the feedback strength, the 1550 nm VCSEL subjected to NOEF emits only in the y-polarizationmode; the x-polarization mode is completely suppressed over the entire current range. Meanwhile, the 1550 nm VCSEL exhibits interesting nonlinear dynamics in the two linear polarized directions when the feedback delay time is varied.
