摘要

The invention is an optical glass amplifier (28) and an amplification optical communication system, all based on a limited length of a single-mode glass fiber made from glass having phonon energy of less than about 350 cm-1 and doped with dysprosium. The glass includes 0.1-30 mol % X, 0-40 mol % arsenic, 0.01-20 mol % gallium, 0.01-20 mol % Y, and 0.001-2 weight % dysprosium, wherein X is selected from the group consisting of germanium and mixtures of germanium and up to 50 % of sulfur; and wherein Y is selected from the group consisting of selenium, indium and mixtures thereof. The system includes a coupler (16), a silica-based signal fiber (10) carrying the optical signal that is to be amplifed in communication with said coupling means (16), a pump light source (18) in communication with the coupler (16), an amplifier (28) in communication with the coupler (16) at one end and another silica-based fiber (32) joined to the amplifier (28) at its other end.
