This project is devoted to the study of the dynamic of two different kind of passive optical systems, in which spatial propagation effects play a fundamental role. The systems are: a) optothermal bistable cavities with localized absorption and multilayer spacers; such dynamical systems have effective dimension determined by the number of layers in the spacer and they seem particularly suitable for studying homoclinic phenomena and specially the Shil'nikov chaos; b) self-induced cavities in saturable absorbers; we study the dynamical evolution of the reflectivity of a system in which a self-reflected wave has been generated. It is a complex dynamic because of the generating position's dependance on intensity.
