We study the dynamics of two Vertical Cavity Surface Emitting Lasers (VCSELs), when they are bidirectionally coupled through the mutual injection of their coherent optical fields. In the long distance limit between the lasers, we focus on the Low Frequency Fluctuations (LFF) regime and we investigate the polarization-resolved dynamics of each laser under the effect of detuning. In the short distance limit, the influence of the propagation phase parameter is also evaluated. For large spin-flip rates, it is found that a change in the propagation phase may induce a sudden switch in the polarization mode that becomes dominant. Extensive simulations scanning the Coupling-Detuning space are performed for both long and short injection delay times.
