Radiation Hardened Silica-Based Optical Fibers.

Abstract

For the defect passivation approach, we have completed the evaluation of the effects of hydrogen treatment. Considerable reduction in radiation-induced absorption at long wavelengths (lamba >1 micron) has been observed for hydrogen-treated fibers. Posttreatment of irradiated fibers by hydrogen also increases the hardness of the fibers under subsequent irradiation. In addition, we found photolumunescence to be an effective characterization tool which provides additional evidence for the passivating effect of hydrogen treatment. Keywords include: Optical fibers, Radiation effects, and Glass structure.
