Abstract
New broadband near infrared luminescence covering the whole work windows (1260–1625 nm) of the current wavelength division multiplexing (WDM) system was found from bismuth-activated M2O–Al2O3–SiO2 (M = Li, Na) and Li2O–Ta2O5–SiO2 glasses at room temperature in the case of 808 nm-laser excitation. But the near infrared luminescence mechanism of the bismuth-activated glasses is not well understood up to now. The figure-of-merits of bandwidth and gain of the glasses are better than those of Er3+-doped silicate glasses and Ti3+ doped sapphire, implying they are the promising gain-medium candidates for the broadband amplifiers and the widely tunable laser sources.
