  • Patent number: 8478084
    Abstract: A device having two sets of raised portions inside a metal case is provided for bending an optic fiber. According to some embodiments, the two sets of raised portions are on two plates that are biased apart by a spring means. According to some embodiments, the metal case prevents viewing of an optic fiber in the metal case. According to some embodiments, an adjustable stopping element is provided to limit movement of the two plates toward each other.

  • Publication number: 20110255828
    Abstract: An article of manufacture is provided that includes an optic fiber comprising a core and a cladding surrounding the core and a sapphire tube bonded to the optic fiber. A total internal reflection surface is positioned such that light guided within the core of the optic fiber reflects off the total internal reflection surface and through the sapphire tube. In other embodiments, a sapphire rod having a total internal reflection surface is fused to an optic fiber comprising a core and a cladding surrounding the core. A glass coating is present on the exterior surface of portions of the sapphire rod such that the glass coating defines an opening that exposes portions of the sapphire rod where light exits the sapphire rod after reflecting off the total internal reflection surface.

  • Patent number: 8009945
    Abstract: A method positions a first end of an optic fiber a distance from a target and applies a laser light to a second end of the optic fiber such that the laser light is guided by the optic fiber from the second end to the first end of the optic fiber and is emitted from the first end of the optic fiber toward the target as a beam of light. The beam of light has a first area of incidence at the target. The optic fiber is then bent such that the beam of light continues to reach the target and such that the area of incidence of the beam of light at the target changes without changing the distance between the first end of the optic fiber and the target. A device having two plates with raised portions inside a metal case is provided for bending the optic fiber.

  • Publication number: 20040190847
    Abstract: A dispersion compensating fiber that includes a segmented core having a refractive index profile with a core segment having a &Dgr;1% greater than 2.0%, a clad layer surrounding and in contact with the core and having a refractive index profile, wherein the refractive index profiles are selected to provide a total dispersion at a wavelength of about 1550 nm of less than or equal to about −177 ps/nm/km, and a total dispersion slope at a wavelength of about 1550 nm of less than or equal to about −2.0 ps/nm2/km. The refractive index profiles are further selected to provide a kappa value, defined as the total dispersion at 1550 nm divided by the dispersion slope at 1550 nm, of greater than or equal to about 67 nm.

  • Patent number: 6563998
    Abstract: Polymer substrates, in particular polyimide substrates, and polymer laminates for optical applications are described. Polyimide substrates are polished on one or both sides depending on their thickness, and single-layer or multi-layer waveguide structures are deposited on the polished polyimide substrates. Optical waveguide devices are machined by laser ablation using a combination of IR and UV lasers. A waveguide-fiber coupler with a laser-machined groove for retaining the fiber is also disclosed.
