Abstract
An optical device includes first and second optical modulators formed on a substrate having electro-optical effect. The first optical modulator includes a first optical waveguide; a first signal electrode configured to provide a first data signal for the first optical waveguide; and a first DC electrode, arranged at an output side of the first signal electrode, and configured to provide first DC voltage for the first optical waveguide. The second optical modulator includes a second optical waveguide; a second signal electrode configured to provide a second data signal for the second optical waveguide; and a second DC electrode provided, arranged at an input side of the second signal electrode, and configured to provide second DC voltage for the second optical waveguide. Input portions of the first and second signal electrodes are arranged at a same side edge of the substrate.
