    Abstract: In an optical modulator, respective lights for where one input light has been branched, are input via a curved waveguide to a plurality of optical modulation sections arranged in parallel on the same substrate. In a Mach-Zehnder type optical waveguide, a spacing between the pair of branching waveguides of the adjacent optical modulation sections, is formed so as to become wider in the vicinity of a border of an input side polarization inversion region than in the vicinity of a start point of an interaction portion. As a result, even if a signal electrode of the optical modulation sections shifts at the boundary portion of the polarization inversion region, the spacing between the signal electrodes does not become narrow, and hence the radius of curvature of curved waveguides for guiding the input light to the respective optical modulation sections can be increased, so that it becomes possible to apply input light to the optical modulation sections at low loss.
