Abstract: A semiconductor device may include a semiconductor wafer, and a reference circuit carried by the semiconductor wafer. The reference circuit may include optical DUTs, a first set of photodetectors coupled to outputs of the optical DUTs, an optical splitter coupled to inputs of the optical DUTs, and a second set of photodetectors coupled to the optical splitter. The optical splitter is to be coupled to an optical source and configured to transmit a reference optical signal to the first set of photodetectors via the optical DUTs and the second set of photodetectors.

Abstract: In one embodiment, a waveguide includes an upstream portion, a downstream portion, and an intermediate portion between the upstream portion and the downstream portion. A first band is disposed on an insulating layer, the first band oriented along a first direction. A first lateral strip and a second lateral strip are disposed on either side of the first band, the first lateral strip and the second lateral strip being thinner or interrupted along the intermediate portion.

Abstract: The disclosure relates to an optical splitter including two waveguides on either side of an axis. Each waveguide includes a first segment and a second segment that are closer to the axis than the rest of the waveguide. The first segments are optically coupled and the second segments are optically coupled. Each guide includes between the first and second segment, starting from the first segment, a first curved section including in succession a curvature the concavity of which is turned the side opposite the axis then a curvature the concavity of which is turned towards the axis, and starting from the second segment a second curved section including in succession a curvature the concavity of which is turned the side opposite the axis then a curvature the concavity of which is turned towards the axis. The first curved sections of the two waveguides are curved differently.

Abstract: A ring resonator electro-optical device includes a first silicon nitride waveguide and a second annular silicon waveguide that comprises a first section running under a second section of the first waveguide. The second waveguide also includes an annular silicon strip having a cross-section increasing in the first section from a minimum cross-section located under the second section.

Abstract: A photonic interconnection elementary switch is integrated in an optoelectronic chip/The switch includes first and second linear optical waveguides which intersect to form a first intersection. Two first photonic redirect ring resonators are respectively coupled to the first and second optical waveguides. Two second photonic redirect ring resonators are respectively coupled to the first and second optical waveguides. A third linear optical waveguide is coupled to one of the first ring resonators and one of the second ring resonators. A fourth linear optical waveguide is coupled to another of the first resonators and to another of the second ring resonators. A base switch, complex switch, and photonic interconnection network integrated in an optoelectronic chip, include at least two of the photonic interconnection elementary switches.
