  • Patent number: 10527800
    Abstract: The present embodiment makes it possible to reduce the height of an optical connection component including a bent optical fiber having a bent-shape part and a fiber fixing component in a safer and more stable manner compared to a conventional technique. Before the fiber fixing component is fixed to the bent optical fiber, formation of a bent portion using the fiber fixing component obliquely disposed and heating of the bent portion are repeated a plurality of times for the optical fiber to which the fiber fixing component is movably fitted. At that time, movement of the optical fiber and the heating of the bent portion are alternately repeated. Thus, a plurality of bent portions where stress is released is formed in the optical fiber along the longitudinal direction thereof.

  • Patent number: 10479720
    Abstract: A method of making optical fibers that includes controlled cooling to produce fibers having a low concentration of non-bridging oxygen defects and low sensitivity to hydrogen. The method may include heating a fiber preform above its softening point, drawing a fiber from the heated preform and passing the fiber through two treatment stages. The fiber may enter the first treatment stage at a temperature between 1500° C. and 1700° C., may exit the first treatment stage at a temperature between 1200° C. and 1400° C., and may experience a cooling rate less than 5000° C./s in the first treatment stage. The fiber may enter the second treatment stage downstream from the first treatment stage at a temperature between 1200° C. and 1400° C., may exit the second treatment stage at a temperature between 1000° C. and 1150° C., and may experience a cooling rate between 5000° C./s and 12,000° C./s in the second treatment stage.

  • Patent number: 10281659
    Abstract: We disclose a modular fiber-interconnect device that can be used in a ROADM to optically interconnect wavelength-selective switches and optical add/drop blocks thereof. An example module of the modular fiber-interconnect device has seventeen optical ports, each implemented using an MPO connector of the same type. The number of (nominally identical) modules in the modular fiber-interconnect device depends on the degree N of the ROADM and can vary, e.g., from two for N=4 to fourteen or more for N?20. A proper set of duplex optical connections within the ROADM can be created in a relatively straightforward manner, e.g., by running MPO cables of the same type from the wavelength-selective switches and the optical add/drop blocks of the ROADM to appropriate optical ports of the various modules of the modular fiber-interconnect device.

    Abstract: A method and system for operating an air jet spinning machine, that features at least one spinning unit with one spinning nozzle for producing a yarn. During normal operation of the spinning unit, a fiber composite is fed to the spinning nozzle through an inlet and in a predefined transport direction. The fiber composite within a vortex chamber of the spinning nozzle receives a twist with the assistance of a vortex air flow, such that a yarn is formed from the fiber composite, which leaves the spinning nozzle through an outlet. After an interruption in yarn production, a piecing process is carried out, with which one yarn end on the spool side moves counter to the transport direction through the spinning nozzle, is overlaid with one end of the fiber composite after passing through the spinning nozzle and, together with this, is brought through the inlet into the spinning nozzle. After conclusion of the piecing process, the production of yarn is continued through the resumption of normal operation.

  • Patent number: 9594220
    Abstract: An optical interface device for optically connecting photonic devices to optical device along with methods of making. The method includes providing a glass support member that is either monolithic or laminated. A laser beam is used to write cores in the body of the support member. The support member includes a bend section and the cores generally follow the bend section and serve to define curved optical waveguides. The cores provide strong out-of-plane optical confinement, thereby allowing for strong bends and therefore a compact design for the optical interface device.

  • Patent number: 9500832
    Abstract: An optical fiber strand holding tool is disclosed for organizing and retaining splice sleeves and fibers from a first fiber bundle during, and optionally after, a splicing activity in which the first bundle is spliced to a second fiber bundle. The apparatus and associated method provide a means of removably securing splice sleeves in an orderly fashion, preventing movement and contamination of the bare fibers during splicing. Magnets and clamping pressure are used separately or in conjunction to provide the retention force. A removable splice retaining portion permits permanent optical joint storage and protection, and reduces handling of the optical joints. Color coded splice sleeves and splice channels are employed for quick matching between fibers in fiber bundle pairs being spliced.

  • Patent number: 9494748
    Abstract: A photonic integrated circuit (PIC) may be optically aligned to a plurality of optical components (e.g., an optical fiber array). Optical alignment may be facilitated by the use of an optical impedance element coupled between a first input/output (I/O) optical waveguide and a second I/O optical waveguide of the PIC. The optical impedance element me be configured to be transmissive during optical alignment and to be non-transmissive during the regular operation of the PIC.

    Abstract: A composite structure having an embedded sensing system is provided, along with corresponding systems and methods for monitoring the health of a composite structure. The composite structure includes composite material and an optical fiber disposed within the composite material. The optical fiber includes a plurality of quantum dots for enhancing its non-linear optical properties. The quantum dots may be disposed in the core, in the cladding and/or on the surface of the optical fiber. The optical fiber is configured to support propagation of the signals and to be sensitive to a defect within the composite material. The quantum dots create a non-linear effect, such as a second order effect, in response to the defect in the composite material. Based upon the detection and analysis of the signals including the non-linear effect created by the quantum dots, a defect within the composite material may be detected.

    Abstract: A multi-core optical fiber may include a cladding with a cross section having a central region and an outside diameter. Multiple transmission cores are arranged symmetrically within the central region of the cladding, extending parallel to a central axis of the multi-core optical fiber. Multiple alignment cores are arranged within the cladding, extending parallel to the central axis of the multi-core optical fiber and near the outside diameter of the cladding so that each of the multiple alignment cores are visible through a side view of the cladding. Ends of similarly configured multi-core optical fibers may be mated and aligned. Alignment cores of a first multi-core optical fiber may be aligned with alignment cores of a second multi-core optical fiber using a side view of the mating interface. Aligning the alignment cores causes multiple transmission cores with the multi-core optical fibers to also align.
