Claim 15:
16. The electro-optical modulator according to claim 1, which implements a Mach-Zehnder interferometer based arrangement, wherein said optical waveguide is a first optical waveguide branch, the modulator further comprising:
a second optical waveguide branch distanced from the first optical waveguide branch along the X-direction and embedded within and/or arranged on the semiconductor substrate, wherein said second optical waveguide branch longitudinally extends along at least the direction transversal to the X-direction; and
a third electrode located distanced from the second electrode along the X-direction, wherein the upper face of said second optical waveguide branch is located at, below or above a location between said second and third electrodes, along said X-direction.
