We study numerically the output polarization of avertical-cavity surface-emitting laser (VCSEL) subject toorthogonal optical injection. We focus on the width of thehysteresis cycle induced by the variation of the detuning of theinjected light. For positive detuning and strong enough opticalinjection we find that the hysteresis width is proportional to thebirefringence parameter; for negative detuning the hysteresiswidth is narrow and is unaffected by the injection strength. Ourresults are in good agreement with recent experimentalobservations.
