GE-GA-S-BASED GLASS COMPOSITION HAVING LIGHT AMPLIFYING CHARACTERISTIC AND APPARATUS FOR OPTICAL COMMUNICATIONS USING THE SAME

摘要

A Ge-Ga-S-based glass composition for performing anoptical amplification and an apparatus for opticalcommunications using the same are provided. In the glasscomposition according to the present invention, an activematerial for performing luminescence and optical amplificationoperations is added to the Ge-Ga-S host glass and a transitionmetal ion moving the distribution of optical amplificationgains is added in a range from 0.07. moleo to 0.2 mol%.
