Fluoride glass fibers

Abstract

Fluoride glass fibers have been first intensively developed for long haut telecommunication applications due to their ultra low theoretical optical loss (0.001 dB/km). After many years of intensive research, unfortunately, this goal has not been reached yet and remains a challenge. In the late nineties, the research activities around fluorides glasses and fibers have slowed down and only a few laboratories continue to have some ongoing activity focusing mainly on short and medium length applications such as fiber lasers, Supercontinuum, spectroscopy and laser power delivery…
