Abstract :
Chaos synchronization properties of vertical-cavity surface-emitting lasers with orthogonal optical feedback and injection are investigated numerically. Based on the spin-flip model, the effects of the feedback strength and the frequency detuning are considered in terms of the cross-correlation coefficient. The results show that there are two regions (i.e., region I and region II) having good synchronization qualities in the space of injection parameters. The outputs in the time domain are further presented to explain the differences between the synchronization properties of region I and of region II.
