Abstract :
We propose and demonstrate a novel fiber-based all-optical regenerator, where the wavelength shift induced by cross-phase modulation is employed for level discrimination. Regeneration of a 10-Gb/s signal using the proposed scheme improves the Q-factor by 1.8 dB. The scheme is stable and robust against changes in environmental conditions.
