Tungsten-niobium-tellurite (TNT) glasses and molybdenum-niobium-tellurite (MNT) glasses have been investigated for their potential application in broadband Raman fiber amplifier. Effects of the addition of heavy metal oxides (HMO) (HMO=Nb2O5, WO3, or MoO3) on the thermal stability against crystallization and Raman spectral properties of tellurite glasses have been discussed. The results suggest that the addition of HMO could largely improve the thermal stabilities of tellurite glasses. Moreover, TNT and MNT glasses exhibit strong Raman peaks at around 848 and 915 cm-1. It is noted that the mid-high frequency Raman region of the tellurite glass by co-doping HMO expand from 550 to 1000 cm-1 with the maximum full width at half maximum (FWHM) of about 375 cm-1, indicating TNT and MNT glasses are promising host-materials for broadband Raman fiber amplification.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
