title: Spectral filtering from a cross-phase modulated signal for RZ to NRZ format and wavelength conversion.
abstract: All-optical return-to-zero (RZ) to non-return-to-zero (NRZ) format conversion has been demonstrated using cross-phase modulation in a dispersion-shifted fiber, which can in principle work with different signal bit rates and does not require any external pulse duplicator. The output wavelength-converted signal is obtained from filtering of the broadened optical spectrum. A power penalty of 2 dB is obtained at 10-9 bit-error-rate level in a 10 Gb/s conversion experiment.
