Abstract
Semiconductor lasers exhibit a wide range of dynamical behaviors such as low frequency fluctuations, coherence collapse, chaos induced by injection, etc [1]. Coupled semiconductor lasers are excellent devices to study the mechanisms leading to chaos synchronization [2]. In this presentation we show experimentally and numerically the existence of lag alternance in two semiconductor lasers coupled unidirectionally via two different paths (Fig. la). The results obtained might shed light into how information is transmitted in a network where the nodes are linked via multiple paths.
