Erbium-Ion-Doped Tellurite Glass Fibres And Waveguides - Devices And Future Prospective: Part 1

This review article focuses on the suitability of Er3+-doped tellurium oxide for optical amplification in fibre, waveguides and as a component for optical integration to meet the emerging demand for broadband and fibre-to-home networks. The importance of the glass structure, in the context of Er3+-ion spectroscopy, is emphasized for dissolving large concentration of dopant ions. The spectroscopic methodologies involved in maximising the gain per unit length of Er3+-doped fibre is explained. In Part II of this study, a review of how the fibre gain data was then employed to engineer amplification in waveguides, which can be integrated with semiconductor pump sources, is presented.
