We have experimentally verified a new idea for 40 Gbit s wavelength conversion within the 1.5 μ m band based on sum-frequency generation (SFG) in a periodically poled Li Nb O 3 waveguide. The spectrum and the temporal waveform of the output pump reveal that the input cw pump is converted to an optical pulse during SFG. Not only wavelength conversion but also a logic NOT gate at 40 Gbit s are experimentally observed.
