High quality soliton loss-compensation in 38 kmdispersion-decreasing fibre

Abstract
The authors report the fabrication of a 38 km soliton loss-compensating dispersion-decreasing fibre with an exponential dispersion profile accurately matched to the fibre loss. High quality loss compensation for 3.5 ps soliton pulses over 38 km (~19 soliton periods) is demonstrated for the first time to the authors' knowledge.
