Abstract

The disclosure proposes an electro-optical modulator, and a corresponding method of fabricating the electro-optical modulator. The electro-optical modulator comprises: a cladding layer; a first and second waveguide core; a ferroelectric layer; and at least two electrodes configured to generate an electric-field across the ferroelectric layer for modulating an optical wave as it passes through the second waveguide core. The ferroelectric layer comprises a first end in the second section, and extends at least in the second section above the first waveguide core, in the third section above the first and the second waveguide core, and in the fourth section above the second waveguide core, wherein in the third section the second waveguide core extends above the first waveguide core, and wherein the second waveguide core is closer to the ferroelectric layer in the fourth section, than the first waveguide core is to the ferroelectric layer in the second section.
