We report wavelength conversion within the 1.5-mu m telecommunications
band based on difference-frequency generation in periodically poled l
ithium niobate waveguides with integrated coupling structures. A conve
rsion efficiency of -7 dB and a normalized efficiency of 260%/W are de
monstrated. Static tests show that the conversion bandwidth is 72 nm a
nd the conversion efficiency is constant over the 20-dB range of input
powers. tested. (C) 1998 Optical Society of America.
