Abstract

The radiation resistivity of multi-mode and single-mode fibers was evaluated. Multi-mode fibers were investigated in terms of the core materials. It was found that the pure silica core fiber comprising pure silica glass produced by the plasma deposition process has excellent radiation resistivity. Further the photobleaching effect on pure silica core fibers was evaluated at room temperature and a low temperature. In investigating single-mode fibers, due attention was paid to the cladding materials. Several pure silica core single-mode fibers with varied BF contents in the cladding were prepared and evaluated. The results revealed that the single-mode fiber with large refractive index difference has better radiation resistivity. Further, a pure silica core and a Ge-doped core single-mode fibers were evaluated for the radiation resistivity at 1.55 μm, which has been rarely reported.
