We demonstrate a multiple-/spl lambda/ wavelength shifter that is based on temporal interleaving and semiconductor optical amplifier cross-gain compression. Our multiple-/spl lambda/ wavelength shifter is transparent to both the nonreturn-to-zero (NRZ) and return-to-zero (RZ) input data-formats. We simultaneously wavelength shift two independent NRZ 1-Gb/s WDM channels from 1548 and 1552 nm to 1540 and 1569 nm, respectively, with low-power penalties.
