Abstract

A Mach-Zehnder modulator includes: first and second resistive elements each having first and second contact areas, the first and second contact areas of the second resistive element being arranged in a direction of a first axis, the first and second contact areas of the second resistive element being arranged in a direction of a second axis; a common conductor connecting the first contact areas of the first and second resistive elements with each other; first and second waveguide structures each including a waveguide portion extending in a direction of a third axis intersecting the first and second axes; a first signal conductor connected to the waveguide portion of the first waveguide structure and the second contact area of the first resistive element; and a second signal conductor connected to the waveguide portion of the second waveguide structure and the second contact area of the second resistive element.
