A new Er3+doped phosphate glass exhibiting an excellent durability in both boiling water and NaNO3 molten salt is developed. The ion-exchange process of this glass is investigated by treating glass samples in a variety of salt baths with various exposure times. A planar waveguide with one mode at 1.54 μm and three modes at 632.8 nm is demonstrated. The spectral properties of Er3+ in this glass are characterized by measuring absorption and emission spectra and fluorescence lifetimes. The emission cross section of Er3+ in this glass is calculated to be 0.76x 1020 cm2 using McCumber theory.
