| Abstract: | By varying the coupling strength, clusters synchronization is found in a ring of four mutually coupled semiconductor lasers with optical feedback. The numerical simulation confirms the mathematical analysis and shows the degree of synchronization in terms of the parameters differences between the lasers. |
