Paper Abstract

This paper reviews recent developments of IR fiber technology in Japan. Fabrication techniques as well as optical characteristics for fluoride fibers are described from the view point of realizing ultra-low-loss fibers aimed at telecommunication applications. A minimum loss of 3 dB/km is achieved for Zr-based fluoride fibers, whose minimum loss is predicted to be less than 0.01 dB/km based on the precise evaluation for intrinsic loss factors. Chalcogenide glass fibers are developed not for telecommunication but for sensing application. The development of other halide crystal and glass fibers is at a basic research level.
