Pr(3+)-doped GeS(x)-based glasses for fiber amplifiers at 1.3 microm.
The photoluminescence properties of Pr(3+)-doped GeS(x)-based glasses are studied and compared with those of other sulfide and fluoride glasses. The possibility of highly pump-power-efficient fiber amplifiers based on these GeS(x)-containing glasses in the telecommunications window at 1.3microm is discussed.
