All-optical signal regeneration with wavelength multicasting has been demonstrated using cross-absorption modulation in a single electroabsorption modulator for the first time. We show that the input signal wavelength can be simultaneously converted to 6 different wavelengths at 10 Gb/s with signal regeneration. The output extinction ratio, the linewidth, and the pulse shape show a significant improvement. A negative power penalty of 2 dB is obtained at 10-9 bit-error-rate level.
