Method for manufacturing electrooptical components comprising an optical structure and an electrical structure on a device, comprising forming at least two optical waveguide structures on a substrate, forming an electrical structure for each optical structure on said substrate, each comprising at least one ground electrode and one signal electrode, respectively associated with said optical waveguide structures, analyzing in succession the optical characteristics of the electrooptical structures constituted by the joining together of said optical structures and said electrical structures formed in accordance with the preceding steps, and choosing one of said electrooptical structures demonstrating, upon said analysis, improved values compared to a predetermined limit; the present invention also relates to electrooptical components comprising independent and symmetrical electrooptical structures.

Cette invention concerne une méthode de fabrication de composants électro-optiques formés d'une structure optique et d'une structure électrique montées sur un dispositif, la structure optique comprenant au moins deux guides d'ondes optiques formés sur un substrat et une structure électrique associée à chacun des guides d'ondes et montée sur le même substrat, lesdites structures électriques comprenant au moins une électrode de masse et une électrode de signal. La méthode prévoit l'analyse itérative des caractéristiques optiques des structures électro-optiques réalisées par assemblage desdites structures optiques et électriques selon ce qui précède, puis le choix de la structure électro-optique qui affiche des valeurs supérieures à un seuil prédéterminé. La présente invention concerne également des composants électro-optiques formés de structures électro-optiques indépendantes et symétriques.
