Abstract:
Provided is an optical waveguide device in which destabilization of a DC bias which is applied to an optical waveguide, due to a bias electrode picking up electric noise, is reduced and an operating characteristic is stable. An optical waveguide device includes: a substrate having an electro-optic effect; an optical waveguide formed on the substrate; a modulation electrode for applying an electric field corresponding to a modulation signal to the optical waveguide; and a bias electrode for applying an electric field corresponding to a DC bias to the optical waveguide, in which in order to reduce capture of electric noise by the bias electrode, with respect to at least a part of the bias electrode, a plurality of electrode portions (b 11 , b 12 ) are formed in at least one (B 1 ) of the pair of electrodes by folding back one electric line.

Claim (Index 2):
An optical waveguide device comprising:\n a substrate having an electro-optic effect; an optical waveguide formed on the substrate; a modulation electrode for applying an electric field corresponding to a modulation signal to the optical waveguide; and a bias electrode for applying an electric field corresponding to a DC bias to the optical waveguide, wherein in order to reduce capture of electric noise by the bias electrode, the bias electrode has at least a pair of electrodes A 2  and B 2  configuring a differential bias electrode, the electrode A 2  has a folded structure with no branched portion, in which a plurality of electrode portions a 2  are disposed in parallel by folding back one electric line, the electrode B 2  has a folded structure with no branched portion, in which a plurality of electrode portions b 2  are disposed in parallel by folding back one electric line, and a part of the electrode portion b 2  is disposed between the electrode portions a 2  disposed in parallel.
