Paper Abstract

The paper presents a study of a single-mode Ti and Fe in-diffusion waveguide. We have reported in this letter the experimental observation of diffraction effects due to the formation of a transitory photorefractive grating. The interference of a guided-wave with light scattering inside the waveguide can form a spatial phase grating due to the photorefractive effect, analogous to the storage process of holograms in bulk crystals. The storage mechanism in these materials is based on light induced permanent changes of the refractive index--the photorefractive effect. In this paper some advantages and limitations of this method are discussed.
