Abstract
A new multi-component optical amplifier glass, composed of multiple glass formers has been developed which displays bandwidths significantly larger than currently possible using silica-based or phosphate based, erbium doped fibers. Initial results indicate that using this material, one could double the bandwidth of existing optical amplifiers. This greatly increased spectrum combined with higher emission cross sections and the ability to go to higher doping concentrations, compared with silica-based fibers, make this new optical amplifier very attractive for increasing the transmission capacity of wavelength-division-multiplexing (WDM) transmission systems using optical fibers.
