An optical waveguide that guides an incident light is formed on an a substrate having an electro-optical effect. A first buffer layer is formed so as to cover the top surface of the substrate. A conductive film is formed above the first buffer layer. A center electrode and a groung electrode are formed to apply voltage to the optical waveguide so as to induce an electric field therein. A second buffer layer is formed between the conductive film and at least one of the center electrode and the ground electrode. The conductive film is so formed as to exist at least a part of and below the ground electrode. Light guided along the optical waveguide is modulated by having the phase thereof changed by voltage applied to the optical waveguide. Accordingly, an optical modulation device is provided that has an excellent electric characteristics by effectively restricting heat drift.

Guide d'ondes optique permettant de guider une lumière incidente, formé sur un substrat et produisant un effet électro-optique. Une première couche tampon est formée de manière à recouvrir la surface supérieure du substrat. Un film conducteur est formé sur cette première couche tampon. Une électrode centrale et une électrode de masse sont formées en vue d'appliquer une tension au guide d'ondes optique pour y induire un champ électrique. Une deuxième couche tampon est formée entre le film conducteur et l'électrode centrale et/ou l'électrode de masse. Le film conducteur est formé de manière à constituer au moins une partie de l'électrode de masse et est situé au-dessous de celle-ci. La lumière guidée par le guide d'ondes optique est modulée par changement de phase grâce à la tension appliquée au guide d'ondes. L'invention permet d'obtenir un dispositif de modulation optique présentant d'excellentes caractéristiques électriques grâce à une restriction efficace du transfert de chaleur.
