Synchronization phenomena in coupled excitable lasers
Excitability has been shown not to be an exclusive property of neuronal cells; it can also be observed in lasers. The results of a numerical study about the synchronization properties in a population of coupled semiconductor lasers with saturable absorber is presented [A. M. Perego and M. Lamperti Physical Review A 94, 033839 (2016)]. It is shown that the coupling between the lasers enable to achieve temporal and intensity synchronization while the cooperative dynamics results in an array-enhanced coherence resonance and synchronization. Further effects such as the possibility of excitability localization will be discussed too.
