Because of the need for broad bandwidth of optical material in optical communication,tungsten-tellurite glass was prepared by means of solid-phase.Its optical properties and thermal stability were studied.Spectral intensity parameters were calculated based on Judd-Oflet theory.According to the McCumber theory,its emission cross section was simulated with a maximum value of 1.85 ×10-20 cm2 and a maximum full width half maximum of 104nm.The thermal stability of glass was analyzed with a maximum differential thermal temperature ΔT of 131℃(difference between glass transition temperature Tg and crystallization temperature Tx).The results show that the erbium-doped tungsten-tellurite glass is a good material for broad bandwidth amplifiers.
