Abstract
We study the onset of synchronization in a network of N delay-coupled stochastic fiber ring lasers with respect to various parameters when the coupling power is weak. In particular, for groups of three or more ring lasers mutually coupled to a central hub laser, we demonstrate a robust tendency toward out-of-phase (achronal) synchronization between the N-1 outer lasers and the single inner laser. In contrast to the achronal synchronization, we find the outer lasers synchronize with zero-lag (isochronal) with respect to each other, thus forming a set of N-1 coherent fiber lasers.
Highlights
The dynamics of delay-coupled systems is a rich and varied area of study covering a wide range of topics from biological systems [1], to chemical reactions [2], to physical systems such as laser systems [3,4] and electrical circuits [5]
We explore the synchronization properties of arrays of fiber lasers where the structure of the network is in a star configuration
We considered a star coupling configuration of N coupled fiber ring lasers in the weak coupling limit
