Zero-lag synchronization in semiconductor lasers (SLs) with mutual coupling interaction has been investigated lately in two, three or even networks of coupled elements. Nevertheless, this type of synchronization may suffer from de-synchronization events within an overall highly correlated synchronized behavior. The intermittent de-synchronization events are noise and/or parameter mismatch induced and have been observed both as fast and frequent events in the coherence-collapse regime and as slower and less-frequent events in the low-frequency fluctuation (LFF) regime, in the case of bi-directionally coupled SLs [1,2].
