QUARTZ OPTICAL FIBER

摘要

PURPOSE:To provide a quartz optical fiber excellent in dispersing characteristics and hardly causing transmission loss. CONSTITUTION:A core part is synthesized by vapor axial deposition so that pure quartz contains germanium enough to increase the refractive index of pure quartz by 0.05% and fluorine enough to reduce the refractive index of pure quartz by 0.03% and the core part is dehydrated and converted into transparent glass by sintering. A clad part is synthesized by external deposition so that pure quartz contains fluorine enough to reduce the refractive index of pure quartz by 0.36% and the clad part is dehydrated and converted into transparent glass by sintering. The refractive index of the core part is higher than that of pure quartz by 0.02% and higher than that of the clad part by 0.38%.
