    Abstract: An optical waveguide termination device includes a waveguide and metal vias surrounding an end portion of the waveguide. The end portion of the waveguide has a transverse cross-sectional area that decreases towards its distal end. The metal vias are orthogonal to a same plane, with the same plane being orthogonal to the transverse cross-section. The metal vias absorb light originating from the end portion when a light signal propagates through the waveguide, and the metal vias and the end portion provide that an effective index of an optical mode to be propagated through the waveguide progressively varies in the end portion. Additional metal vias may be present along the waveguide upstream of the end portion, with the additional metal vias bordering the waveguide upstream of the end portion providing that the effective index of an optical mode to be propagated through the waveguide varies progressively toward the end portion.

    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: A photonic integrated circuit includes an optical coupling device situated between two successive interconnection metal levels. The optical coupling device includes a first optical portion that receives an optical signal having a transverse electric component in a fundamental mode and a transverse magnetic component. A second optical portion converts the transverse magnetic component of the optical signal into a converted transverse electric component in a higher order mode. A third optical portion separates the transverse electric component from the converted transverse electric component and switches the higher order mode to the fundamental mode. A fourth optical portion transmits the transverse electric component to one waveguide and transmits the converted transverse electric component to another waveguide.

    Abstract: An optical waveguide is configured to propagate a light signal. Metal vias are arranged along and on either side of a portion of the optical waveguide. Additional metal vias are further arranged along and on either side of the optical waveguide both upstream and downstream of the portion of the optical waveguide. The metal vias and additional metal vias are oriented orthogonal to a same plane, the same plane being orthogonal to a transverse cross-section of the portion of the optical waveguide.
