  • Publication number: 20260036740
    Abstract: A hollow core optical fiber preform including a seal at least partially sealing one or more of a cladding opening of a cladding tube and a capillary opening of each or some of one or more capillary tubes within a cladding interior of the cladding tube. The hollow core optical fiber preform includes a seal glass composition exhibiting a seal coefficient of thermal expansion that is within ±10% of a coefficient of thermal expansion of the cladding or a coefficient of thermal expansion of the one or more capillaries. The hollow core optical fiber perform can further include one or more metal tubes extending through the seal. The metal tubes can be placed in fluid communication with one or more sources of a gas to control gas pressure within the one or more capillary tubes and the cladding interior during a draw step to control the dimensions thereof.

  • Publication number: 20260028265
    Abstract: A method of manufacturing a hollow core optical fiber from a hollow core optical fiber preform is disclosed, the method including measuring a first dimension of the hollow core optical fiber while drawing the hollow core optical fiber from the hollow core optical fiber preform, comparing the measured first dimension with a predetermined target range, and adjusting a first preform property of the hollow core optical fiber preform if the measured first dimension is outside of the predetermined target range while drawing the hollow core optical fiber from the hollow core optical fiber preform.

  • Publication number: 20150177732
    Abstract: Optical fibers and optical fiber tapers have application within many optical systems and optical devices. To date manufacturing such fibers and fiber tapers has been restricted to drawing constant diameter fibers in gravity driven processes and symmetric tapers through pulling with localized heating. However, it would be beneficial to be able to generate arbitrary profiles when pulling an optical fiber into a fiber taper allowing an initial uniform section, reducing transition, wire section, increasing transition and final uniform section.

  • Patent number: 8660395
    Abstract: There is described an optical waveguide structure exhibiting nonlinear properties, a method of fabricating such, and an optical coupling device made of two of such optical waveguide structures. The optical waveguide structure comprises an optical waveguide portion made of a light transmitting material for supporting a light mode traveling therein. The light transmitting material has an intrinsic nonlinearity parameter suitable for inducing a nonlinearity on the light mode, and the optical waveguide portion having a diameter sized to securely confine the light mode therein and to increase the nonlinearity on the light mode. The optical waveguide structure also has a coating surrounding the optical waveguide portion to mechanically support or to protect the optical waveguide portion from surface damage.
