Delay-Coupled Laser Networks: Complex Behavior, Synchronization and Applications — •Ingo Fischer — IFISC (Instituto de Física Interdisciplinar y Sistemas Complejos), Campus UIB, 07122 Palma de Mallorca, Spain

Semiconductor lasers are known to be very sensitive to external feedback, as well as to input from other lasers. This sensitivity, due to the nonlinear interaction of lasing field and semiconductor medium and the unavoidable delays in feedback and coupling, often results in emerging complex behavior. At the same time the nonlinear interactions lead to synchronization phenomena. For a long time such behavior has been considered undesired and difficult to treat experimentally and theoretically. Recently, tools to treat these systems have been developed, coupled lasers are serving as testbed systems for delay-coupled networks and suggestions for applications have been proposed. In this presentation we provide examples of the advances and discuss the perspectives of such systems.
