Ultralong Raman fibre lasers as virtually lossless optical media

Ania-Castañón, Juan D.; Ellingham, Tim J.; Ibbotson, Robin A.; Chen, Xianfeng F.; Zhang, Lin and Turitsyn, Sergei K. (2006). Ultralong Raman fibre lasers as virtually lossless optical media. Physical review letters, 96 (2), 023902.


By transforming the optical fiber span into an ultralong cavity laser, we experimentally demonstrate quasilossless transmission over long (up to 75 km) distances and virtually zero signal power variation over shorter (up to 20 km) spans, opening the way for the practical implementation of integrable nonlinear systems in optical fiber. As a by-product of our technique, the longest ever laser (to the best of our knowledge) has been implemented, with a cavity length of 75 km. A simple theory of the lossless fiber span, in excellent agreement with the observed results, is presented.
