• Resumen

  • The field of optical nonlinear dynamics can be divided in two subfields: the study of the temporal dynamics and the study of spontaneous pattern formation. As an example of temporal dynamics, we refer to periodic or chaotic spike sequences observed in the output of lasers. When considering the spatial extent of optical systems, a wealth of spatial patterns is found in broad-area lasers and cavities filled with a nonlinear medium. Most of these spatio-temporal phenomena encountered in optical systems can also be observed in a variety of other disciplines such as hydrodynamics, 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.
