Abstract: An E/O phase modulator may include a waveguide having an insulating substrate, a single-crystal silicon strip and a polysilicon strip of a same thickness and doped with opposite conductivity types above the insulating substrate, and an insulating interface layer between the single-crystal silicon strip and polysilicon strip. Each of the single-crystal silicon strip and polysilicon strip may be laterally continued by a respective extension, and a respective electrical contact coupled to each extension.

Abstract: A method of manufacturing an integrated circuit including photonic components on a silicon layer and a laser made of a III-V group material includes providing the silicon layer positioned on a first insulating layer that is positioned on a support. First trenches are etched through the silicon layer and stop on the first insulating layer, and the first trenches are covered with a silicon nitride layer. Second trenches are etched through a portion of the silicon layer, and the first and second trenches are filled with silicon oxide, which are planarized. The method further includes removing the support and the first insulating layer, and bonding a wafer including a III-V group heterostructure on the rear surface of the silicon layer.

Abstract: A method is for making a photonic chip including EO devices having multiple thicknesses. The method may include forming a first semiconductor layer over a semiconductor film, forming a second semiconductor layer over the first semiconductor layer, and forming a mask layer over the second semiconductor layer. The method may include performing a first selective etching of the mask layer to provide initial alignment trenches, performing a second etching, aligned with some of the initial alignment trenches and using the first semiconductor layer as an etch stop, to provide multi-level trenches, and filling the multi-level trenches to make the EO devices having multiple thicknesses.

Abstract: The present disclosure relates to a method including the following steps: a) forming a waveguide from a first material, the waveguide being configured to guide an optical signal; b) forming a layer made of a second material that is electrically conductive and transparent to a wavelength of the optical signal, steps a) and b) being implemented such that the layer made of the second material is in contact with at least one of the faces of the waveguide, or is separated from the at least one of the faces by a distance of less than half, preferably less than a quarter, of the wavelength of the optical signal. The application further relates to a phase modulator, in particular obtained by such a method.
