摘要：

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 mu m 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 0.76 x 10(20) cm(2) using McCumber theory. (C) 1998 Society of Photo-Optical Instrumentation Engineers. [S0091-3286(98)02012-1].
