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. © 2006 Wiley Periodicals, Inc.
