Tellurite fibers

Nov. 1, 1998

Tellurite fibers, made by KDD, are rare-earth fibers with potential for use in erbium-doped fiber tellurite fiber amplifiers for dense WDM applications. The gain bandwidth of the erbium-doped tellurite amplifier is about 80 nm (more than twice the bandwidth of erbium-doped silica fiber amplifiers). Tellurite can be pumped at 980 or 1480 nm.
