Abstract
A significant challenge occurs when two Mach-Zehnder optical modulators are placed in close proximity next to one another, resulting in substantial cross talk. An optical modulator configured to reduce crosstalk between adjacent optical modulators includes a positive polarity signal electrode electrically coupled between a driver and an optical phase shifting section, and a negative polarity signal electrode electrically. The positive polarity signal electrode comprises a first positive polarity signal electrode section extending adjacent to a first optical waveguide path, and a second positive polarity signal electrode section extending adjacent to a second optical waveguide path. The negative polarity signal electrode comprises a first negative polarity signal electrode section extending adjacent to the second optical waveguide path and the first positive polarity signal electrode section, and a second negative polarity signal electrode section extending adjacent to the first optical waveguide path and the second positive polarity electrode section.
