Estimativa computacional de efeitos na propagação da luz surgentes em meios ópticos fotorrefrativos

Abstract

Optics consists of the field that aims to study the nature of light and the phenomena resulting from its propagation and interaction with matter, currently being a powerful source of new technologies. As an inherently electromagnetic phenomenon, light causes changes in the positions, orientations, or shapes of material components, eliciting a response from materials that is sometimes nonlinear in the presence of light. Despite being a relatively recent discovery in optics, such nonlinear phenomena constitute a broad source of modern technologies, especially in computer science and communication systems. Our work aims to study the arising effects in the propagation of light in photorefractive media, where the nonlinear response of the material alters the refractive index in proportion to the intensity of the propagating light, as well as to estimate through numerical methods the propagation of light in these media and compare them to behaviors in optical media whose response to light is purely linear.
