Abstract
Phase modulation electrode lines of a semiconductor Mach-Zehnder optical modulator are formed along waveguides. Output-side lead lines are bent in a direction crossing the extending direction of the waveguides in the plane of a dielectric layer and are connected to terminal resistors. The output-side lead lines are formed in a predetermined width corresponding to a desired impedance and make the width narrower than the predetermined width only in the bent portions and portions where the output-side lead lines crosses the waveguides.
