Zusammenfassung:The present disclosure provides a waveguide line electrode structure and an electro-optic modulator. The waveguide line electrode structure is additionally provided with a covering layer located above an optical waveguide, and an electrode extension portion connected to a signal electrode or a ground electrode extends to an upper surface of the covering layer. By means of the waveguide line electrode structure according to embodiments of the present disclosure, it is ensured that a distance between an electrode extension portion for the signal electrode and an electrode extension portion for the ground electrode is close enough, and it is also ensured that there is a certain distance between the electrode extension portion and the corresponding optical waveguide. Therefore, by means of the waveguide line electrode structure according to the present disclosure, electro-optical conversion efficiency is increased, and normal transmission of light in a first branch or light in a second branch is prevented from being affected, such that a modulation effect of the waveguide line electrode structure is significantly improved.
