Abstract

The radiation induced optical transmission loss of heat-treated fused silica core optical fibers has been investigated under gamma-ray irradiation. Observed radiation induced transmission loss indicated temperature dependence, which suggests that the behavior of radiation induced defects responsible for the transmission loss depend on heat-treatment temperatures before irradiation. As a result, the optical fibers heat-treated at 200 °C had the most radiation resistance among those investigated. We propose that an optimum temperature for developing radiation resistance should exist and might be near 200 °C.
