METHOD AND APPARATUS FOR FORMING AN OPTICAL FIBER PREFORM BY COMBUSTIONLESS HYDROLYSIS |
| 摘要 |
The present invention relates to a method and apparatus for fabricating a glass preform used in the manufacture of optical waveguides. The method utilizes a gas phase hydrolysis of a silica precursor without using a carrier gas. The flow of the reactants in the reaction chamber is confined and deposited on the target preform by careful control of the thermal profile in the system. |
