Abstract

Holographic photorefractive gratings in optical waveguides with high photorefractive sensitivity on lithium niobate can be used for an information input in integrated-optical-vector- matrix multiplication devices. An influence of the Fe and Cu additional diffusion on the refractive index profile of LiNbO<SUB>3</SUB>:Ti waveguides and their photorefractive properties has been investigated and a matrix component input in the device with acousto-optical vector component input are demonstrated.
