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.

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 multicore optical fiber that includes seventeen cores arranged in a hexagonally close-packed configuration, each core having a core center and comprising silica and an up-dopant; and a cladding region surrounding the seventeen cores, the cladding region having a cladding edge, an outer diameter, and a cladding composition comprising silica. The outer diameter of the cladding region is between about 100 microns and 150 microns. Further, the hexagonally close-packed configuration has bi-lateral symmetry to accommodate bi-directional data flow within the fiber.

Abstract: Assemblies, optical connectors, and methods for bonding optical elements to a substrate using a laser beam are disclosed. In one embodiment, a method of bonding an optical element to a substrate includes disposing a film layer on a surface of the substrate, disposing the optical element on a surface of the film layer, and directing a laser beam into the optical element. The method further includes melting, using the diameter laser beam, a material of the substrate to create a bond area between the optical element and the surface of the substrate. The film layer is capable of absorbing a wavelength of the laser beam to melt the material of the substrate at the bond area. The bond area includes laser-melted material of the substrate that bonds the optical element to the substrate.
