  • Patent number: 11698485
    Abstract: A method of manufacturing a multimode optical fiber includes specifying a peak wavelength ?P for the multimode optical fiber. The peak wavelength ?P corresponds to a wavelength at which the multimode optical fiber has a maximum bandwidth. The multimode optical fiber comprises a core and a cladding surrounding and directly adjacent to the core. The core has a radius r1 and a maximum relative refractive index ?1,MAX>0. The cladding comprises a depressed-index region having a minimum relative refractive index ?3,MIN<0 and a volume v. A draw tension T for the multimode optical fiber is selected based on a correlation relating peak wavelength ?P to draw tension T, the correlation comprising a correlation constant. The correlation constant K is a function of at least one of ?1,MAX, r1, v, ?3,MIN, and ?P. The multimode optical fiber is drawn from a preform at the draw tension T.

  • Publication number: 20230110293
    Abstract: A method of categorizing a group of multimode optical fibers, the method including comparing an effective modal bandwidth of a first multimode optical fiber with a first threshold, the first multimode optical fiber being in a group of multimode optical fibers meeting a first OM-standard and the first threshold being an effective modal bandwidth of the first multimode optical fiber. The method further including categorizing the first multimode optical fiber as meeting OM functional requirements of a second OM-standard if the effective modal bandwidth of the first multimode optical fiber is equal to or above the first threshold, wherein the second OM-standard is higher than the first OM-standard.

  • Publication number: 20230094509
    Abstract: Methods for classifying a core cane of an multimode optical fiber are disclosed. In embodiments, the method includes determining a relative refractive index profile ?(r) of the core cane; fitting the relative refractive index profile ?(r) to an alpha profile ?fit(r) defined by: ? fit ( r ) = ? o , fit ( 1 - ( r a fit ) ? fit ) where ?o,fit is a relative refractive index at a longitudinal centerline of the core cane, ?fit is a core shape parameter, and afit is an outer radius of the core cane; generating a non-alpha residual profile ?diff(r)=?(r)??fit(r) for the core cane; computing one or more metrics from ?diff(r), and using the one or metrics in a classification of the core cane, the classification comprising a prediction of whether a bandwidth at a pre-determined wavelength of an optical fiber drawn from a preform comprising the core cane exceeds a pre-determined bandwidth at the pre-determined wavelength.

  • Patent number: 11530157
    Abstract: A method of manufacturing a tuned optical fiber includes providing a first preform from a set of like preforms each having substantially the same refractive index profile, including amount of axial variation relative to a target refractive index profile. The method includes drawing a reference optical fiber from the first preform and measuring a variation in an optical or physical property as a function of axial position. The method also includes drawing from a second preform from the set of like preforms the tuned optical fiber. The drawing includes using a time-varying tension that reduces the amount of variation of the optical or physical property of interest. The time-varying tension is defined by an amount of axial stress imparted to the tuned fiber needed to alter the refractive index profile and the at least one optical or physical property based on a stress-optic effect.

  • Publication number: 20050209556
    Abstract: A device and method are described for the delivery of cells, tissues, enzymes and/or pharmacological agents for the treatment or prevention of diseases, disorders or deficiencies. The device is placed intravascularly and includes a chamber that houses living cells delimited by a membrane on either side that physically separates the cells from the blood stream and the central lumen of the catheter. The device can be inserted over a guidewire and permits flushing and reloading of the central lumen with viability supporting factors that sustain the cells in the outer chamber for long indwelling times without removing it from the body. In addition, the central lumen can be used to deliver therapeutic substances or withdraw blood.
