  • Method of depositing a layer of silica followed by a step of adding dopant to the layer
    Patent number: 6532775
    Abstract: A method of manufacturing an optical fiber preform (3) comprising: forming at least one silica-based outer deposition layer (23) by depositing silica on a primary preform (24) constituted by a bar mainly comprising silica and including a silica-based outer peripheral portion (22), the method being characterized in that the viscosity of the outer deposition layer (23) is adjusted to be substantially identical to the viscosity of the outer peripheral portion (22) of the primary preform (24) by adding to the silica, over a substantial portion of the outer deposition layer (23), at least one compound selected from the group formed by the following compounds: CaF2, MgF2, AlF3, B2O3, and Al2O3.

  • Multi-core optical fiber
    Patent number: 6097868
    Abstract: The multi-core optical fiber comprises cores embedded in common cladding, with each core containing a dopant. A "peculiar" one of the cores has a central zone that is not doped by the dopant, the other cores all being completely doped by the dopant, thereby enabling the peculiar core to be used as a local reference point in order to locate the cores of the optical fiber individually.
