  • Publication number: 20140116995
    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.

  • Patent number: 8702322
    Abstract: An optical fiber connector preloaded with an adhesive is provided. The optical connector includes an optical fiber-receiving passage. The passage includes a first passage section extending inwardly from the first face, and the first passage section has a first width. The passage includes a second passage section extending inwardly from the second face, and the second passage section has a second width. The second width is less than the first width. The passage includes a transition passage section located between the first passage section and the second passage section. The transition passage has a variable width, and the variable width of the transition section decreases as the distance to the second face decreases. A meltable adhesive composition is located within the transition passage section and is configured to bind an optical fiber to an inner surface of the second passage following melting and solidification of the adhesive composition.

  • Publication number: 20140105545
    Abstract: A ferrule for optical waveguides includes an exterior and an interior of the ferrule. The interior of the ferrule has a bore defined therein that is configured to receive an optical waveguide. Material of the ferrule is such that the material changes from the interior to the exterior of the ferrule, where the thermal expansion coefficient of the material transitions from less than 30×10?7/° C. at the interior of the ferrule to greater than 70×10?7/° C. at the exterior of the ferrule. The thermal expansion coefficient of the material may change by way of discrete layers in the material between the interior and exterior of the ferrule.

  • Publication number: 20130343709
    Abstract: Embodiments disclosed herein include ferrule assemblies employing mechanical interfaces for optical fibers and related component and methods. The ferrule assemblies may be used in fiber optic connectors to precisely position the optical fiber relative to the ferrule to facilitate an optical connection with another optical device. In certain embodiments disclosed herein, the ferrule assemblies include a ferrule that includes an inner surface forming a ferrule bore. Each of the ferrules may also include an end portion of an optical fiber disposed in the ferrule bore. The inner surface of the ferrule bore abuts against an outer surface of the optical fiber to form a mechanical interface. In this manner, the mechanical interface secures the optical fiber within the ferrule bore and precisely positioned relative to the ferrule. This mechanical interface may eliminate the need for epoxy or other means to secure the optical fiber within the ferrule bore.

  • Publication number: 20130343710
    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.

  • Publication number: 20130336618
    Abstract: A pre-terminated optical fiber assembly with a ferrule having front and rear opposed faces and at least one fiber bore defined longitudinally therethrough includes a glass optical fiber is disposed within the at least one fiber bore with the fiber fused to the ferrule at a location at least 1 mm deep inside the bore. A method for fusing is also disclosed. The ferrule 14 is desirably composed of an inorganic composite material, the composite comprising a material gradient from at least 75% by volume of a first inorganic material to at least 75% by volume of second inorganic material in the radially inward direction, where the first inorganic material has a fracture toughness of at least 1 MPa•m1/2, and the second inorganic material has a softening point of no greater than 1000° C., desirably no greater than 900° C.

  • Patent number: 8052836
    Abstract: Laser-based methods of stripping different types of fiber optic cables (100) are disclosed. The method includes directing a focused laser beam (202) onto the cable's protective cover (114). The method also includes moving the fiber optic cable relative to the focused laser beam in a direction substantially along a central axis (AC) to form a substantially axially oriented groove (250) in the protective cover, wherein the groove does not reach one or more optical fibers (110) carried by the cable. The method can further include opening the protective cover at the groove to form a split protective cover portion (114S), and removing the split protective cover portion from the fiber optic cable. Methods of stripping a cable by forming two grooves in the protective cover using two focused laser beams are also disclosed.
