SYNTHESISING THE F-DOPED SILICA TUBE USING THE SOL-GEL PROCESS

摘要

The F-doped silica tube was synthesised using the sol-gel process. The synthesised silica tube has lower refractive index, OH content and metal impurities compared with the commercial silica tube for optical fiber. The optical fiber made from the synthesised F-doped silica tube has the minimal loss of 0.44 dB/km at 1.58 um.
