Modeling Synchronization in Networks of Delay-Coupled Fiber Ring Lasers

摘要

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.
