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,—Ga,S,stoichiometric composition line with a rare earth element, and further contains 0.1˜10 atomic % of a halogen element base on the Ge—Ga—S glass. By using optical fiber, clustering of praseodymium (Pr,) ions can be suppressed even when the concentration of added Pr,is high, thereby improving light amplification efficiency.
