The all-optical wavelength conversion gives flexibilities to the optical fiber communication
networks, especially to the wavelength-division-multiplexed (WDM)-based ones, because it allows
them to reuse wavelengths and to avoid wavelength channel contentions [l-21. Recently, we
proposed a novel cross-phase modulation (XPM) wavelength converter that had a directionallycoupled
semiconductor optical amplifier (DCSOA) structure, and reported its preliminary results of
simulation,
