Erbium-Ion-Doped Tellurite Glasss Fibers and Waveguides - Devices and Future Prospective: PART Ⅰ

摘要

This review article focuses on the suitability of Er~(3+)-doped tellurium oxide glass for optical amplification in fiber, waveguides and as a component for optical integration to meet the emerging demand for broadband and fiber-to-home networks. The importance of the glass structure, in the context of Er~(3+)-ion spectroscopy, is emphasized for dissolving large concentrations of dopant ions. The spectroscopic methodologies involved in maximizing the gain per unit length of Er~(3+)-doped fiber is explained. In Part Ⅱ of this study, a review of how the fiber gain data was then employed to engineer amplification in waveguides, which can be integrated with semiconductor pump sources, is presented.
