Abstract
Two unidirectionally coupled external cavity semiconductor lasers showing c haotic intensity fluctuations are studied by numerically solving the Lang-K obayashi model equations [IEEE J. Quantum Electron. QE-16, 347 (1980)]. The systems are shown to synchronize when operating in the regime of low-frequ ency fluctuations, which is characterized by a very high-dimensional (d>150 ) attractor. The influence of parameter differences between the two lasers on the synchronization quality is investigated. [S1063-651X(98)02512-4].
