  • Method of centering a fiber core in a multiple-crucible method
    Patent number: 6588235
    Abstract: The invention relates to a method of making an optical fiber and an optical fiber made in accordance with the inventive method. The method includes the step of drawing an optical fiber from a multiple crucible apparatus, wherein one of the crucibles of the apparatus has a non-symmetrical orifice (not shown). The inventive fiber has at least a core and cladding. At least one section of the inventive fiber includes an orientation element.

  • Process for drawing optical fiber from a multiple crucible apparatus with a thermal gradient
    Patent number: 6550279
    Abstract: The disclosed invention includes a method of making an optical fiber drawn from a multiple crucible. The method includes moving a first crucible of the multiple crucible relative to a second crucible of the multiple crucible. The invention also includes minimizing core and cladding diffusion. A tip of the first crucible is disposed axially above a tip of the second crucible by a preselected distance. The invention further includes the ability to alter a diameter of the core of the fiber. A differential pressure is applied to the first crucible. A positive differential pressure is applied to increase the core diameter. A negative differential pressure is applied to decrease the core diameter. Furthermore, the invention includes drawing the fiber under non-isothermal conditions; there is a thermal gradient of at least 10° C./m between the two tips.
