“…But enhancement of IPDR using pre-amplifier is still insufficient for system applications. To overcome this drawback, controlling the bias current of pre-amplifier in XPM wavelength converter has been studied (Endo et al 2002), even at XGM wavelength converter (Bang et al 2000). Using this method, the power of pre-amplified XPM wavelength converter falls on to satisfy the desired input power range of XPM wavelength converter.…”

The performance of pre-amplified cross-phase modulation (XPM) wavelength converter with a continuous wave (CW) holding beam has been theoretically investigated. To increase the input power dynamic range of the pre-amplified XPM wavelength converter, we apply a CW holding beam to the pre-amplifier of XPM wavelength converter. In our proposed scheme, the input power dynamic range with negative power penalty of 20dB was obtained.Keywords XPM wavelength converter · Pre-amplifier · Input power dynamic range · CW holding beam
