Paper Abstract

In this paper we report the optical properties of Er-doped silica fibers. The fibers were produced from glasses obtained by sol-gel method. Luminescence spectra of Er3+ ion were measured in monolithic glass samples after excitation by a xenon lamp, as well as in the fiber after excitation by an IR 980 nm diode laser. It was found that under the IR excitation, a green emission at 540 nm was observed due to the up-conversion effect. This effect is associated with the aggregation of Er ions and constitutes an important factor reducing the efficiency of 1.55 micrometers emission.
