Ti : LiNbO3 Electrooptical Active Components for Integrated Optics

Abstract

In this paper we shall present the results obtained at Thomson-CSF in the. realization of active electrooptical components using the diffusion of Titanium in LiNb03 Crystals. We shall discuss in details the switching problem and in particular the conditions required to obtain good switching efficiency and the different configurations that can be used. Recent experimental results concerning the directional coupler switch with different configurations will be given.
