Wavelength exchanging technologies modeling, comparison, and validation

Simultaneous power exchange between two input signals, has been theoretically and experimentally demonstrated based on two phenomena: Four Wave Mixing (FWM) in High-Linear Dispersion Shifted Fiber (HNL-DSF) and Three Wave Mixing (TWM) in NonLinear Photonic Crystals (NL-PC). These phenomena have been used in many applications in WDM optical networks such as, wavelength conversion, wavelength sampling, optical 3R, optical interconnects and optical add-drop multiplexing. In this work, numerical simulation of the exchanging process is presented to compare the performance of using these components in WDM optical networks using Matlab-Simulink.
