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.
