Complex phenomena in photonics, in particular, dynamical properties of semiconductor
lasers due to delayed coupling, are reviewed. Although considered a nuisance for a long …

We review chimera patterns, which consist of coexisting spatial domains of coherent
(synchronized) and incoherent (desynchronized) dynamics in networks of identical …

Nonlinear systems with two competing frequencies show locking or resonances. In lasers,
the two interacting frequencies can be the cavity repetition rate and a frequency externally …

Qu'est-ce que le passé, sinon du présent qui est en retard? Pierre Dac (l'osa moelle, March
1940) Modeling automatic engines or physiological systems often involves the idea of …

We show that isochronous synchronization between two delay-coupled oscillators can be
achieved by relaying the dynamics via a third mediating element, which surprisingly lags …

In this volume, six review articles which cover a broad range of topics of current interest in
modern optics are included. The first article by S. Saltiel, AA Sukhorukov and YS Kivshar …

Background Coupled biological oscillators can tick with the same period. How this collective
period is established is a key question in understanding biological clocks. We explore this …

Stability of synchronization in delay-coupled networks of identical units generally depends in
a complicated way on the coupling topology. We show that for large coupling delays …

For a globally coupled network of semiconductor lasers with delayed optical feedback, we
demonstrate the existence of chimera states. The domains of coherence and incoherence …

Rhythmic and sequential subdivision of the elongating vertebrate embryonic body axis into
morphological somites is controlled by an oscillating multicellular genetic network termed …
