Abstract: Waveguide substrate connection systems and methods are provided herein. An example waveguide assembly comprises a first substrate having a first waveguide, a second substrate having a second waveguide, an adhesive, and one or more spacers. A height for the one or more spacers is less than 10 ?m. The adhesive and the one or more spacers provide a composite material configured to assist in securing the first substrate and the second substrate together to align the first waveguide and the second waveguide. When the first substrate and the second substrate are attached together via the adhesive, the one or more spacers are configured to maintain a desired gap spacing therebetween so as to optimize coupling efficiency between the first waveguide and the second waveguide. The desired gap spacing corresponds to the height for the one or more spacers.

Abstract: The disclosure relates to methods of fabricating of ceramic structures, and more particularly to methods of fabricating ceramic structures having profiled surfaces and more particularly to methods of fabrication of ceramic mirror blanks. In one embodiment, a method of forming a shaped ceramic article, includes: forming, via one of a cold-pressing process or pressure casting process, a green ceramic article comprising a first surface, an opposing second surface and at least one high aspect ratio feature shaped into at least one surface; heating the green featured ceramic part to form a debound featured ceramic part; and densifying the debound featured ceramic part via one of a pressureless sintering process or a hot-pressing process.

Abstract: The glass-based ferrules include a glass substrate and two spaced-apart guide tubes, which can also be made of glass. The guide tubes include bores sized to receive guide pins from another ferrule. The ferrule can be used to form an optical interconnection device in the form of a waveguide connector that includes a planar lightwave circuit that supports multiple waveguides. The ferrule can also be used to form an optical interconnection device in the form of a fiber connector that includes a support substrate and an array of optical fibers supported thereby. The waveguide connector and fiber connector when mated form an integrated photonic device. Methods of forming the ferrule components, the ferrules and the optical interconnection devices are also disclosed.

Abstract: The fiber array assemblies include an interdigitated signal-fiber array supported on a support substrate and formed by front-end sections of first signal fibers interdigitated with either front-end sections of second signal fibers or spacer fibers. The assemblies also include a fiber pusher device that may comprise glass and first and second ends. The fiber pusher device is disposed so that its first and second ends contact and push against first and second edges of the interdigitated signal-fiber array to remove gaps between adjacent signal fibers. A cover sheet is disposed atop the interdigitated signal-fiber array and covers at least a portion of the fiber pusher device to define a ferrule. A securing material is disposed within a ferrule interior to secure the cover sheet, the interdigitated signal-fiber array and the fiber pusher devices. The fiber array assemblies can be connectorized by adding an interconnect device or the like.
