摘要： A photonic chip is disclosed that comprises a cladding material and an edge coupler. The edge coupler comprises a composite guiding structure that comprises a plurality of substantially parallel planar layers of optical guiding material. Each layer of the composite guiding structure extends into the cladding material, wherein each layer is aligned at a first edge of the photonic chip. The layers overlap along a first axis which is perpendicular to a plane of the planar layers of optical guiding material. The photonic chip is arranged for deposition of a waveguide on the cladding material, the waveguide being arranged to at least partially overlap along the first axis with a layer of the composite guiding structure.
Also disclosed is a method of manufacturing a photonic chip.

摘要： The present disclosure includes an optical fiber ribbon, using polymer optical fibers and an extremely thin adhesive coating to provide adhesion between the fibers. The external surfaces of the optical fiber ribbons are precisely placed with respect to the optical cores of the constituent fibers, and the optical cores of the fibers are precisely placed with respect to each other. Therefore, the external surface of the ribbon is used as a reference surface for aligning the array of optical fiber cores to arrays of optical emitters or detectors at the ends of the ribbon. Thus, the optical fiber ribbon of the present disclosure is cut, either by a sharp blade or other tool as suitable to expose a cross-section of the ribbon, and inserted as a single unit into a receptacle that aligns the outer surface of the ribbon with respect to the array of optical emitters or detectors.
