1. A push-pull device, comprising:
a first waveguide arranged between a first electrode and a second electrode related to the first waveguide,
a second waveguide arranged between a first electrode and a second electrode related to the second waveguide,
one or more electrically conductive structures extending away from one or more of the electrodes and electrically connecting at least two of the electrodes,
the waveguides and the electrodes originating from a pre-fabrication process,
the waveguides being poled by a poling originating from a poling process which includes applying an electrical field between at least two of the electrodes,
the electrically conductive structures originating from the pre-fabrication process,
wherein one or more of the electrically conductive structures extend to one or more electrically non-conductive gaps,
wherein the device further comprises one or more electrically conductive elements for electrically connecting two of the electrodes, the electrically conductive elements being related to the electrically non-conductive gaps and originating from a post-fabrication process, and
wherein the one or more of the electrically conductive elements is arranged at the one or more of the electrically non-conductive gaps.
