Claim 20:
21. The method according to claim 20, comprising using a criterion based on requirements of target optical bandwidth and target optical transmission to be met by the electro-optical modulator, to determine the lengths to be provided to:
at least one of the top and bottom graphene sheets to respectively extend along the X-direction above the optical waveguide width, or completely above the whole width of the optical waveguide and beyond through a respective further projecting portion, and/or,
at least one of the further top and further bottom graphene sheets to respectively extend along the X-direction above the width of the second optical waveguide branch, or completely above the whole width of the second optical waveguide branch and beyond through a respective further projecting portion.
