High-resolution spectroscopy of ions in optical fibers

Abstract

Spectroscopy of ions in optical fibers is of particular interest for two distinct reasons. The first instance has become increasingly obvious as communications networks use active fiber elements as amplifiers in the 1.55μm band and progress toward a useful fiber amplifier in the 1.3μm band continues. These fiber amplifiers have greatly increased the scope of fiber communications, and the understanding of the detailed spectroscopy of rare-earth ions such as erbium in glass matrices has become increasingly important. Equally, the changes in optical properties of dopant ions on pulling fibers from bulk material is also important for the production of practical devices.
