Abstract :
The authors investigate a possible technique, based on a three stage cascade configuration, in order to implement an all-optical 3R regenerator. A multiwave-mixing based unit is used to perform simultaneously reshaping, re-amplification and wavelength conversion of a propagated signal. A fiber ring based unit is used to perform the all-optical timing extraction while a classical four-wave-mixing process inside a dispersion-shifted fibre is adopted for the retiming process.
