xPbO–(1 − x)GeO2 glasses as potential materials for Raman amplification

Raman amplification presents a huge potential for optical communications. xPbO–(1 − x)GeO2 glasses (with x = 0, 10%, 20%, 30% and 40% mol) are studied. The association of lead oxide and germanate is thought to be a suitable candidate for Raman amplification regarding to its high scattering level and the large plateau existing on its Raman scattering spectra. The estimated optimal composition is 0.36PbO–0.64GeO2.
