Two types of synchronization in unidirectionally coupled chaotic external-cavity semiconductor lasers.
We study numerically two distant unidirectionally coupled single-mode semiconductor lasers subject to coherent optical feedback. We show that two fundamentally different types of chaotic synchronization can occur depending on the strengths of the coupling and of the feedback of the receiver laser.
