ResumenNonlinear dynamics in photonic systems is an e ervescent field that has been continuously evolving during the last decades. The field of optical nonlinear dynamics can be divided in two subfields, namely the study of the temporal dynamics in nonlinear optical systems — assuming that the spatial structure of the light field does not change in time — and the study of spontaneous pattern formation in those systems. As an example of temporal dynamics, we refer to e.g. periodic or chaotic spike sequences that have been observed in the output of lasers. When considering the spatial extent of optical systems, a wealth of spatial patterns has been found in e.g. broad-area lasers and cells filled with sodium vapor. Most of these spatio-temporal phenomena encountered in optical systems can also be observed in a variety of other disciplines such as hydrodynamics, electrical discharges, chemical and biological systems, etc., because they refer to universal concepts and essentially share the same mathematical formalism. In this thesis, we address both temporal and spatial dynamics in optical systems. In Part I, we study the dynamical behavior of semiconductor ring lasers, while in Part II we examine nonlinear dynamics of spatially localized structures in extended systems.
