Recent progress of wavelength conversion and all-optical signal processing in periodically poled lithium niobate (PPLN) waveguides is reported. Applications for optical communications in the near-infrared, as well as for tuneable absorption spectroscopy in the mid-infrared are highlighted. Novel waveguide structures and fabrication methods are presented.
