Abstract
Disclosed herein is a low phonon energy glass and a fiber made therefrom. e glass includes the following components given in mol percent: ______________________________________ germanium 0.1-30 arsenic 0-40 X 0.01-20 Y 40-85 ______________________________________ wherein X is selected from the group consisting of gallium, indium and mixtures thereof wherein Y is selected from the group consisting of selenium, and mixtures of selenium and up to 50% of sulfur substituted for selenium and the glass also contains 0.001-2 weight percent of a rare earth, based on the weight of said components. The fiber has a minimum loss of less than 5 dB/m.
