Abstract

An all-optical wavelength conversion based on the cascaded second-order nonlinear interactions of Sum-and Difference-Frequency Generation（SFG+DFG） in quasi-phase matched Periodically Poled LiNbO

（PPLN） Waveguides with a dual-pulse pump source is studied.A theoretical model for the description of the SFG+DFG wavelength conversion is developed.The process of the wavelength conversion is analyzed by numerical simulation and walk-off effect and pulse broadening have been observed in pulse propagations.The study shows that the conversion efficiency is affected by the length of the waveguides

signal wavelength and pulse width.
