Abstract

A new Er³⁺ doped phosphate glass exhibiting an excellent durability in both boiling water and NaNO₃ molten salt was developed. Ion-exchange process of this glass was investigated by treating glass samples in a variety of salt bathes with various exposure times. Planar waveguide with one mode at 1.54 micrometers and three modes at 632.8 nm was demonstrated. Spectral properties of Er³⁺ in this glass were characterized by measuring absorption and emission spectra, and fluorescence lifetimes. Emission cross section of Er³⁺ in this glass was calculated to be 0.76 X 10^-20 cm² using McCumber theory. Our preliminary experimental results indicate this new Er³⁺ doped glass is an excellent material for ion-exchanged waveguide lasers and amplifiers.
