  • Patent number: 9205609
    Abstract: A method is provided of fabricating an optical fiber having a polished end face, including providing an optical fiber having an axis; positioning and maintaining the axis A of the fiber, at a specific location along the fiber, at a fixed position; and forming a laser processed end face on the individual fiber at said specific location L by irradiating the individual fiber at said location with one or more laser beams while moving the one or more laser beams in a rotational direction around the fiber. The method may be applied to a jacketed fiber and/or a fiber on a reel. Resulting fibers are also disclosed.

  • Patent number: 9205610
    Abstract: Head-on laser shaping of optical surfaces on optical fibers, related assemblies and methods are disclosed. By “head-on laser shaping,” a laser beam is directed in a laser beam path collinear or substantially collinear to the longitudinal fiber axis of an end portion of an optical fiber. The end face of the end portion of optical fiber is exposed to the laser beam to laser shape a polished optical surface in the end face of the optical fiber. In this manner, the entire surface area of the end face of the optical fiber can be exposed to the laser beam during laser shaping, making it unnecessary unless desired, to rotate the optical fiber or laser beam during laser processing. The cross section energy distribution of the laser beam can also be controlled to laser shape an optical surface in the end face of the optical fiber of the desired geometry.

  • Publication number: 20150301292
    Abstract: A method of terminating an optical fiber involves providing a ferrule having a front end, a rear end, a ferrule bore extending between the front and rear ends, and a bonding agent disposed in at least a portion of the ferrule bore. The method also involves applying energy to heat the bonding agent. An end section of an optical fiber is inserted into the ferrule bore and through the bonding agent when the bonding agent is heated. The end section of the optical fiber includes a primary coating prior to insertion into the ferrule bore. During insertion of the end section of the optical fiber through the bonding agent, the heated bonding agent thermally removes at least a portion of the primary coating during so that the optical fiber can be secured in the ferrule bore with the bonding agent.

  • Patent number: 9151905
    Abstract: Embodiments disclosed herein include pre-terminated fiber optic connector sub-assemblies, and related fiber optic connectors, cables, and methods. In certain embodiments, an optical fiber stub is pre-installed in a ferrule bore of a ferrule of a fiber optic connector sub-assembly, to provide the pre-terminated fiber optic connector sub-assembly. The optical fiber stub can be pre-installed in the ferrule bore prior to termination of the fiber optic connector sub-assembly. Because the pre-terminated optical fiber stub disposed in the ferrule bore is not directly accessible through a ferrule body of the ferrule when a field optical fiber is disposed in the ferrule bore for fusion splicing, the ferrule has properties that allow thermal energy to be directed through the ferrule body into the ferrule bore. In this manner, the optical fiber stub pre-installed in the ferrule bore can be fusion spliced with the field optical fiber to terminate a fiber optic cable.

  • Publication number: 20150277048
    Abstract: An optical fiber includes a glass fiber, having a cladding and core, surrounded by a polymer coating. Some of the coating is removed by a laser beam so that the optical fiber comprises a first lengthwise portion covered by the coating and a second lengthwise portion where the coating is not present on at least ninety-five (95) percent of an exterior surface of the second lengthwise portion. A microstructure of the polymer coating, adjacent to the second lengthwise portion on the first lengthwise portion, tapers at an angle such that a thickness of the polymer coating decreases toward the second lengthwise portion as a function of proximity to the second lengthwise portion. The optical fiber may also be optionally cleaved with the laser beam.

  • Publication number: 20150219860
    Abstract: A method of securing an optical fiber to a ferrule involves heating the ferrule to cause thermal expansion. A ferrule bore of the ferrule increases in diameter as a result of the thermal expansion, and an optical fiber is inserted into the ferrule bore. The ferrule is then cooled so that the ferrule bore decreases in diameter and forms a mechanical interface with the optical fiber. Finally, the optical fiber is fused to the ferrule by irradiating the optical fiber and the ferrule with laser energy.

  • Patent number: 9085047
    Abstract: Coating removal systems for optical fibers are disclosed. Related methods and optical fibers processed with these methods and coating removal systems are also disclosed. An optical fiber includes a glass fiber, having a cladding and core, surrounded by a protective coating which does not contribute to the optical performance of the optical fiber. By removing the coating at an end portion of the optical fiber, the end portion may be precisely positioned and secured to enable reliable optical communications. A laser beam may be directed at the protective coating to remove the protective coating by one or more ablating, melting, vaporizing, and/or thermal decomposing processes. The optical fiber may also be optionally cleaved. In this manner, the coating may be efficiently removed while retaining at least fifty percent of the tensile strength of the optical fiber.

  • Patent number: 8985866
    Abstract: Simultaneous thermal forming of a ferrule and optical fiber as part of a ferrule assembly to thermally form an optical surface in the ferrule assembly. Related fiber optic components, connectors, assemblies, and methods are disclosed. In certain embodiments, the ferrule assembly is comprised of a ferrule and an optical fiber having an end portion extending from an end face of the ferrule. The ferrule may be made from a material or material composition having the same or similar thermal energy absorption characteristics as the optical fiber disposed in the ferrule. Thus, when the end face of the ferrule and an end portion of an optical fiber are simultaneously exposed to a wavelength(s) of a laser beam emitted by a laser, at least a portion of the end face of the ferrule and end portion of the optical fiber are both thermally formed together to form an optical surface.

  • Patent number: 8916072
    Abstract: Gradient-index (GRIN) lens fabrication employing laser pulse width duration control, and related components, systems, and methods are disclosed. GRIN lenses can be fabricated from GRIN rods by controlling the pulse width emission duration of a laser beam emitted by a laser to laser cut the GRIN rod, as the GRIN rod is disposed in rotational relation to the laser beam. Controlling laser pulse width emission duration can prevent or reduce heat accumulation in the GRIN rod during GRIN lens fabrication. It is desired that the end faces of GRIN lenses are planar to facilitate light collimation, easy bonding or fusing of the GRIN lens to optical fibers to reduce optical losses, polishing to avoid spherical aberrations, and/or cleaning the end faces when disposed in a fiber optic connector, as non-limiting examples.
