Wavelength conversion of a 6 /spl times/ 40 Gb/s DPSK WDM signal using FWM in a highly non-linear photonic crystal fiber

We demonstrate FWM wavelength conversion of a 6/spl times/40 Gb/s DPSK WDM signal In HNL-PCF. We show a conversion efficiency better than -20.3 dB for 25 dBm pump power and a power penalty less than 4.1 dB for all channels.
