Abstract: A process for forming a fluidic module (150) with integrated fluid separation includes positioning a first positive passage mold (115A) of a first fluid passage (170) having a tortuous shape within a volume of binder-coated ceramic powder (110A) and positioning a second positive passage mold (115B) of a second fluid passage (175) having a tortuous shape within the volume of ceramic powder (110A) and spaced apart from the first positive passage mold (115A). The process further includes positioning a powder interconnect (120) adjacent to a portion of each of the first (115A) and second positive passage molds (115B) within the volume of ceramic powder (110A), pressing the volume of ceramic powder (110A, HOB) with the first and second positive passage molds (115A, 115B) and the powder interconnect (120) inside to form a pressed body (148), heating the pressed body to remove the first and second positive passage molds (115A, 115B), and sintering the pressed body (148) to form a closed-porosity ceramic body (150).

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: Fiber array spacers, optical fiber assemblies, optical assemblies, and methods for fabricating optical assemblies are disclosed. In one embodiment, an optical fiber assembly includes a fiber array spacer and a fiber ribbon having an array of optical fibers. The fiber array spacer has an array of spacer fibers, wherein individual spacer fibers of the array of spacer fibers are bonded to one another, and a diameter of the individual spacer fibers determines a height of the fiber array spacer. Each optical fiber of the array of optical fibers has an glass portion. The glass portion of each optical fiber is bonded to the fiber array spacer such that a longitudinal axis of the individual spacer fibers is transverse to a longitudinal axis of individual optical fibers of the fiber ribbon.

Abstract: A high stiffness substrate for optical elements is described. The substrate includes a graphite finishing layer and a non-oxide ceramic base substrate. The non-oxide ceramic base substrate is preferably a carbide, such as boron carbide or silicon carbide. The graphite finishing layer may include a surface with low finish. Low finish may be achieved by diamond turning the graphite surface. The graphite finishing layer may be joined to the non-oxide base ceramic with a solder. A supplemental finishing layer may be formed on the graphite finishing layer. A reflective stack may be formed on the graphite or supplemental finishing layer. Methods for making the substrate are also described.

Abstract: Assemblies, optical connectors, and methods for bonding optical fibers to a substrate using a laser beam are disclosed. In one embodiment, a method of bonding an optical fiber to a substrate includes directing a laser beam into the optical fiber disposed on a surface of the substrate, wherein the optical fiber has a curved surface and the curved surface of the optical fiber focuses the laser beam to a diameter that is smaller than a diameter of the laser beam as it enters the optical fiber. The method further includes melting, using the laser beam, a material of the substrate at a bond area between the optical fiber and the surface of the substrate such that the optical fiber is bonded to the surface of the substrate.
