Alkali halide-doped sulfide glasses for optical amplifier and fabricating method thereof

摘要

There is provided alkaloid halogen-doped sulfide glasses for an optical amplifier and a fabricating method thereof. An alkaloid halogen-doped sulfide glass is formed of silica doped with a Ge—Ga—S three-component system, Pr^3+, and an alkaloid halogen. To fabricate the alkaloid halogen-doped sulfide glass for an optical amplifier, silica doped with Ge, Ga, S, Pr^3+, and an alkaloid halogen as a starting material is filled into a container. The container is sealed in a vacuum and the starting material in the container is fused by heating the container. The container is cooled and the starting material is sintered by heating the container at a glass transition temperature.
