Paper Abstract

In this work, we report the optical properties of Tm3+, Er3+, and Tm3+-Er3+ codoped tellurite TeO2-WO3-PbO glasses for different Er3+ and Tm3+ concentrations. Judd-Ofelt intensity parameters have been determined to calculate the radiative transition probabilities and radiative lifetimes of excited states of Tm3+ and Er3+ ions. Luminescence spectra and lifetimes were measured under 793 nm and 800 nm excitations. The infrared emission of Tm3+ at 1470 nm is broader by around 30 nm and the stimulated emission cross section twice if compared to fluoride glasses used for S-band amplifiers. Moreover, a broad emission from 1350 to 1600 nm with a full width at half-maximum of ~ 160 nm is obtained by codoping the glass with Tm2O3 an Er2O3 which suggests these glasses could be promising materials as broadband light sources and broadband amplifiers for wavelength-division-multiplexing (WDM) transmission systems.
