    Abstract: A device includes a first directional coupler and a second directional coupler. A first arched waveguide forms a first curved optical path between a first output port of the first directional coupler and a first input port of the second directional coupler. The first arched waveguide has an angle of curvature and a radius of curvature. A second arched waveguide has the angle of curvature and the radius of curvature. The first arched waveguide and the second arched waveguide each have a concavity oriented in the same direction. A first straight waveguide is coupled to a second output port of the first directional coupler and a first end of the second arched waveguide. A second straight waveguide is coupled to a second end of the second arched waveguide and a second input port of the second directional coupler.

    Abstract: A method includes providing a semiconductor body comprising a surface with a recessed portion therein. The recessed portion includes a bottom surface. Optical waveguide cores in a first array of optical waveguide cores extend side-by-side at the bottom surface. The method further includes providing a second array of optical waveguide cores over the first array of optical waveguide cores. Optical waveguide cores in the second array of optical waveguide cores extend side-by-side. Each optical waveguide core in the second array of optical waveguide cores is in an adiabatic coupling relationship with a corresponding optical waveguide core in the first array of optical waveguide cores. The method also includes applying an optical waveguide cladding material over the second array of optical waveguide cores.

    Abstract: An optical demultiplexer includes an interleaver with at least four ports including a first port adapted to receive the sum of two optical signals A and B, a second port and a third port respectively for signals A and B, and a fourth port. The optical demultiplexer further includes an optical component coupled to at least one of the two ports for signals A and B and configured to split the optical signal to be outputted into a weak intensity optical signal and a strong intensity optical signal.
