GeO2-P2O5-Doped Silica Graded-Index Optical Fibers Fabricated by a New Profile-Control Technique
Summary :
The new profile-control technique was investigated in regard to the modified CVD method to reduce OH-ion concentration in GeO2-P2O5-doped silica graded-index optical fibers. The new profile-control technique, in which only exygen flow rate is varied for a parabolic radial index profile, was successfully attained by utilizing effects of exygen on properties of the deposited glass layer. Amounts of GeCl4 gases, which do not react with oxygen, exist in the heated zone of a supporting tube and can effectively eliminate H2O contaminations by the new profile-control technique. A GeO2-P2O5-doped silica graded-index optical fiber was obtained, that simultaneously has a high transmission bandwidth of 1.5 GHz・km and OH-ion absorption loss of 0.9 dB/km at 1.39 µm.
