Two unidirectionally coupled external cavity semiconductor lasers showing chaotic intensity uctuations are studied by numerically solving the Lang-The systems are shown to synchronize when operating in the regime of low-frequency uctuations which is characterized by a very high-dimensional (d > 150) attractor. The innuence of parameter diierences between the two lasers on the synchronization quality is investigated.

We investigate the detrimental effects of parameter mismatch on the synchronization of semiconductor lasers with electro-optical feedback, whose intensity dynamics can display a hyperchaotic behavior. Analytical techniques are developed to study the statistical properties of the synchronization error as a function of the various types of mismatches. The multiple mismatch case, which is of high ...
