Abstract

Ge-doped silica-core optical fiber waveguides are attractive for optical communication systems requiring all-glass fibers with low loss and high bandwidth; indeed, many of the all-glass fibers now commercially available are based on the germanium-silica system. In spite of their attractive intrinsic properties, we showed at the Second Topical Meeting on Optical Fiber Transmission¹ and in more-recent studies^2,3 that these fibers suffer severe degradation in optical transmission when exposed to radiation.
