Abstract :
Yttria-alumina-silica (YAS) glasses doped with Er3+ and Tm3+ have been examined spectroscopically for their potential as fiber amplifier gain media for optical telecommunication systems. Absorption and emission spectra as well as emission lifetime measurements and Judd-Ofelt calculations are reported. Tm3+: YAS glass exhibits an emission bandwidth of 122 nm around 1470 nm, making it promising for S+-band amplification.
