Push-pull device and method for fabricating a push-pull device

A method for fabricating a push-pull device, comprising:

• a pre-fabrication process, which includes:
• arranging a first waveguide between a first electrode and a second electrode related to the first waveguide,
• arranging a second waveguide between a first and a second electrode related to the second waveguide,
• arranging one or more electrically conductive structures which extend away from one or more of the electrodes to at least one electrically non-conductive gap,
• a poling process, which includes applying an electrical field between at least two of the electrodes,
• a post-fabrication process, which includes:
• arranging at least one electrically conductive element related to the at least one electrically non-conductive gap for electrically connecting two of the electrodes,
• wherein the post-fabrication process includes arranging one or more of the at least one electrically conductive element at one or more of the at least one electrically non-conductive gap.
