A waveguide including a substrate, an assembly of semiconductor regions consecutively extending on the substrate along a direction corresponding to a propagation direction of an electromagnetic wave having a wavelength noted &#x3bb;, the semiconductor regions being electrically alternately doped with a first conductivity type and with a second conductivity type along the propagation direction, a dielectric layer interposed between two consecutive semiconductor regions, at least one pair of consecutive elementary structures having a dimensions along the propagation direction adapted to &#x3bb; to form a grating where the light propagates with no diffraction effects.

Waveguide for an electro-optic capacitive modulator

A method of manufacturing an optical waveguide with a vertical slot including the steps of a) providing a substrate successively including an electric insulator layer and a crystalline semiconductor layer, b) forming a trench on the semiconductor layer to expose the electric insulator layer and defining first and second semiconductor areas on either side, step b) being executed so that the first semiconductor area has a lateral edge extending across the entire thickness of the semiconductor layer, c) forming the dielectric layer having the predetermined width across the entire thickness of the lateral edge, the method being remarkable in that the trench formed at step b) is configured so that the second semiconductor area forms a seed layer.
