METHOD OF CONTROLLING FLUORINE DOPING IN SOOT PREFORMS |
| 摘要 |
A method for controlling the refractive index achieved using a fluorine dopant gas, wherein CF4 is employed as the dopant gas, and the soot preform is doped using the CF4 for a time and temperature sufficient to result in a decrease in fluorine dopant nearest the surface which is in contact with the CF4 gas. |
