Paper Abstract

The wavelength conversion based on cascaded second-order nonlinearity by using pulsed pump waves is theoretically analyzed in a periodically poled lithium niobate waveguide. By numerical simulation, the evolution of pulses and the walk-off between pulses is discussed, and a distorted waveform of converted pulse is illustrated. A tunable and single-to-dual-channel wavelength converter is realized by pumping with picosecond pulses at a repetition rate of 40 GHz, and the waveform distortion of a converted pulse is demonstrated in our experiments.
