Query: In phase and anti-phase syncronization of coupled homoclinic oscillators   We numerically investigate the dynamics of a closed chain of unidirectionally
coupled oscillators in a regime of homoclinic chaos. The emerging
synchronization regimes show analogies with the experimental behavior of a
single chaotic laser subjected to a delayed feedback
