Tunable all-optical wavelength conversion of 160 Gbit/s RZ signals based on cascaded SFG-DFG in PPLN waveguide

We first report on error-free tunable all-optical wavelength conversion of 160 Gbit/s return-to-zero signals based on cascaded sum-frequency and difference-frequency generation in a periodically poled LiNbO/sub 3/ waveguide. The BER of less than 10/sup -9 /is achieved in 23 nm tuning range.
