Abstract

Single made fibre soliton transmission is of great interest for high bit rate-long haul optically amplified links [1], but requires in-line frequency-guiding filters to decrease temporal fitter of the soliton pulses [2], We here report the realization of asymetrical UV-written fibre Fabry-Pérot filter suitable for both frequency-guiding of WDM soliton transmission and equalization, to compensate, for instance, the asymetries brought between the different channels by the erbium-doped fibre amplifier gain. Such solution offers filter fabrication simplicity, straightforward splicing to other fibres, and extremely low insertion loss.
