Abstract: A method and corresponding apparatus for processing optical fiber include directing light from a directed light source toward an optical fiber on a fiber draw. A fiber core of the optical fiber is heated, using at least the light from the directed light source, to a fiber core temperature within a glass transformation temperature range of the fiber core. The method can be used to reduce fictive temperature of the fiber core, with Rayleigh scattering being reduced, leading to lower attenuation losses in the fiber core.

Each photon entanglement chain includes at least one quantum repeater structurally configured to entangle a pair of photons and first and second terminating quantum memories optically coupled the quantum repeater using the multicore fiber links such that photons received by the first and the second terminating quantum memories are entangled with photons entangled by the quantum repeater. The first and second terminating quantum memories of each of the two photon entanglement chains form first and second cross-chain quantum repeaters, and the first and the second photon detector units are structurally configured to receive the measurable entangled particles generated by the first and second cross-chain quantum repeaters, respectively.

Abstract: A fiber sensor that includes: an optical fiber configured for one of single or few mode operation at a wavelength from about 300 nm to about 2000 nm, and further defined by a transmission end, a scattering end, a fiber outer diameter and a fiber length from about 10 m to about 100 km. The fiber includes: a plurality of cores having equivalent core diameters and compositions; and a cladding defined by the fiber outer diameter and surrounding the cores. The fiber is tapered at the transmission end to define a tapered portion characterized by a tapered fiber out diameter and tapered core diameters smaller than the respective fiber outer diameter and core diameters. Further, the transmission end of the fiber exhibits a total backscattered signal that emanates from the cores after light from a single source has been injected into the cores at the transmission end of the fiber.

Abstract: The embodiments described herein relate to multi-core optical fiber interconnects which include at least two multi-core optical fibers. The multi-core optical fibers are connected such that the core elements of the first multi-core optical fiber are optically coupled to the core elements of the second multi-core optical fiber thereby forming an array of interconnect core elements extending through the optical fiber interconnect. The multi-core optical fibers are constructed such that cross-talk between adjacent core elements in each multi-core optical fiber is minimized. The multi-core optical fibers are also constructed such that time-delays between the interconnect core elements in the array of interconnect core elements are also minimized.

Abstract: An optical fiber with low fictive temperature along with a system and method for making the optical fiber are provided. The system includes a reheating stage that heats the fiber along the process pathway to a temperature sufficient to lower the fictive temperature of the fiber by relaxing the glass structure and/or driving the glass toward a more nearly equilibrium state. The fiber is drawn from a preform, conveyed along a process pathway, cooled and subsequently reheated to increase the time of exposure of the fiber to temperatures conducive to lowering the fictive temperature of the fiber. The process pathway may include multiple reheating stages as well as one or more fiber-turning devices.
