An electro-optic element comprising a ferroelectric substrate comprising a single crystal having an electro-optic effect, in which an optical waveguide is formed by thermal diffusion of titanium in a main face, and in which an axis in which said electro-optic effect is induced is parallel to said main face; a heat treated buffer layer provided on said ferroelectric substrate on a side in which said optical waveguides are formed; electrodes provided on a part of the buffer layer; and a protective film for preventing contamination of the buffer layer provided on at least the region of the buffer layer on which the electrodes are not formed.

Composant optoélectronique consistant en un substrat ferroélectrique constitué par un monocristal exerçant un effet optoélectronique. Ce substrat possède un guide d'ondes optique dont une surface principale comporte du titane thermodiffusé et dont l'axe le long duquel l'effet optoélectronique est induit, est parallèle à ladite surface; une couche tampon thermotraitée située sur la surface principale, une électrode située sur une partie de la couche tampon et une couche de protection située au moins dans une zone dans laquelle l'électrode n'est pas placée sur la couche tampon, de manière à empêcher la contamination de ladite couche.
