Abstract

The choice of rare earth additive when doping chalcogenide glasses can affect their mid-infrared fiber performance. Three praseodymium additives, Pr-foil, PrCl3 and PrI3 are investigated in Ge-As-Ga-Se fibers. All the fibers are X-ray amorphous and the Pr(foil)-doped fiber has the lowest overall optical loss. Pumping at 1550 nm wavelength, the Pr3+-doped fibers exhibit photoluminescence across a 3.5 to 6 ?m span; photoluminescence lifetimes are 10 ms for 3H5?3H4 and 2-3 ms for (3H6, 3F2)?3H5 transitions. A fast 0.21 ms decay for (3F3, 3F4)?3H6 is observed only in the PrCl3-doped fiber due to a lower phonon energy local environment of Pr3+ ions.
