Abstract
An optical fiber for use in a light amplifier. The optical fiber is formed by doping a gerrnanium-gallium-sulfur (Ge--Ga--S) glass containing less sulfur than a GeS.sub.2 --Ga.sub.2 S.sub.3 stoichiometric composition line with a rare earth element, and further contains 0.1.about.10 atomic % of a halogen element base on the Ge--Ga--S glass. By using optical fiber, clustering of praseodymium (Pr.sup.+3) ions can be suppressed even when the concentration of added Pr.sup.+3 is high, thereby improving light amplification efficiency.
