Abstract :
We report the first demonstration of high bitrate, polarisation insensitive optical phase conjugation and wavelength conversion using orthogonally polarised fibre distributed feedback lasers as four-wave mixing pumps in both dispersion shifted fibre and semiconductor optical amplifier. We report the use of a novel optical phase conjugator configuration in 20/40 Gbit/s WDM network system experiments. The conjugator uses inline fibre distributed feedback (DFB) lasers as pumps and polarisation independent operation is achieved by aligning the polarisations orthogonally
