✦ Synopsis


Single-to-dual channel wavelength conversion at 40 Gbit/s is experimentally observed based on sum-frequency generation and difference-frequency generation in periodically poled LiNbO 3 waveguides. Wavelength relationships between dual-channel idler waves and three incident waves are investigated in detail. The results imply that dual-channel idler wavelengths and channel spacing can be controlled by appropriately tuning two pump wavelengths.
