A. Locquet et al., Two types of synchronization in unidirectionally coupled chaotic external-cavity semiconductor lasers - art. no. 045203, PHYS REV E, 6404(4), 2001, pp. 5203
We study numerically two distant unidirectionally coupled single-mode semic
onductor lasers subject to coherent optical feedback. We show that two fund
amentally different types of chaotic synchronization can occur depending on
the strengths of the coupling and of the feedback of the receiver laser.
