Generalised synchronisation in laser devices with electro-optical feedback

The authors report on partial and global generalised synchronisation in exemplar bi-directionally coupled non-identical chaotic systems with multiple time delays. The authors derive conditions for such synchronisation regimes. The general approach is applied to the case of multiple time-delay laser systems with electro-optical feedback. The authors also study the effect of signal sampling on the signatures of time delays in the autocorrelation function of the multiple time-delay laser output.
