Abstract

Thermo-luminescence behavior of fused silica (SiO₂) core optical fibers was studied in the air under the &ggr; ray irradiation. The thermo-luminescence peak at 1390nm, being attributed to the oxyhydrate (OH) in the fused silica had an expected temperature dependence of the intensity and could be used as a temperature monitor. A partially replaced core optical (PARCO) fiber that consists of a fiber doped with high content of OH inserted into a pure silica fiber was proposed to realize a spatial resolution.
