Abstract

The purpose of this work is the Study of Photorefractives Materials and their Applications in Optical and Holographic Information Processing. The process that makes possible these applications is the photorefractive effect. Thus, we study the propagation and coupling of electromagnetic waves in photorefractives materials: Bi12SiO20 (BSO) and Bi12TiO20 (BTO), and LiNbO3-doped and -undoped; both in bulk and fibers form. We use techniques of holographic characterization and nonlinear optics, for determination of parameters and figures of merit of these photorefractive medium. Also, present some applications, as: the use as holographic memories of high capacity of storage; and Non-Destructive Tests, as Real-Time Holographic Interferometry.
