Paper Abstract

The defect driven properties of erbium doped fiber amplifier devices are reviewed examining the role of the host dopants, aluminum, phosphorus and germanium, typically used in these applications. The effects of added loss on the performance of amplifiers are shown by way of modeling. Measurements of the gamma and UV radiation induced absorption are presented to show the generic host glass composition effects on radiation induced loss and their relative magnitude. In contrast to these `bad' defects, the UV induced effects in H2 impregnated fiber are discussed in their role as `good' defects, allowing the more efficient writing of UV induced gratings.
