Abstract
A Mach-Zehnder optical modulator with a travelling wave electrode having one or more signal transmission line conductors and one or more ground transmission line conductors is provided. The modulator includes a ground strip conductor extending substantially in parallel to the ground transmission line conductors, and a distributed bridging structure electrically connecting the ground strip conductor and at least one of the ground transmission line conductors along a substantial portion of a length thereof. The distributed bridging structure may be embodied by a plurality of electrical connections at disposed regularly spaced intervals.
