The authors demonstrate and characterize a transparent all-optical wavelength conversion process for subcarrier-multiplexed channels. Their memoryless /spl chi//sup (2)/:/spl chi//sup (2)/ difference-frequency-generation process uses 1550-nm pumping in a periodically poled lithium niobate waveguide. They achieve penalty-free all-optical wavelength conversion of two 55-Mb/s subcarrier channels. The process shows a >30-dB linear dynamic range for crosstalk-free transparent operation.
