Abstract: An optical structure includes an input waveguide, a beam splitter, a first arm, a second arm, a beam combiner, and an output waveguide. The first arm and the second arm each include a conventional waveguide region and a modulation waveguide region. The modulation waveguide region of the first arm includes a first modulation waveguide region and a second modulation waveguide region. The modulation waveguide region of the second arm includes a third modulation waveguide region and a fourth modulation waveguide region. The electrical structure includes a traveling wave electrode including a ground-signal-signal-ground electrode structure. The traveling wave electrode includes a signal input region, a modulation electrode region, and a matching resistor region. The modulation electrode region includes a first modulation electrode region and a second modulation electrode region. The first modulation electrode region is connected to the second modulation electrode region.
