Hydrogen Bonds Between Peroxy Radicals and Hydrogen Molecules in SiO2 Glass
Optical fibers are one of the most important components supporting communication systems in these modern days. Many studies have been devoted to clarifying the mechanism of loss increment caused by hydrogen-diffusion which affects adversely the long-term reliability of optical communication systems. In addition to the absorption band at 1.24 μm caused by hydrogen molecules1 and the one spreading from 1.39 to 1.4l μm caused by OH groups2, the absorption bands at 1.42, 1.45 and 1.52 μm are known to be related to hydrogen3,6. Among them, the absorption at 1.52 μm is important because it influences the transparency at 1.55 μm where single-mode fibers are operated. In this paper, the cause of this absorption is discussed.
