Title: Manufacturing method of base material of optical fiber
Inventor: YOKOYAMA YOSHIO
IPC: C03B37/018
Filed: 2000-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing an optical fiber base material that contains plural regions with different refractive indexes in a core, by which a process adding a dopant to a clad region is simplified. SOLUTION: Double-cored base material 1a is formed from a first core region 10 to which a first dopant Ge raising the refractive index is added, and a second core region 20 consisting of pure SiO2. A fine particle glass layer for the clad is formed over the material 1a by using a raw material gas which contains a second dopant F decreasing the refractive index, then is sintered, thus causing the result that optical fiber base material 1 having a clad region 30 in which the dopant F is added to the outside of the double core is formed. A cost reduction by simplifying the process is realized because there is no impregnation process for adding the second dopant F before the sintering process.
