AbstractA tunable and stability-enhanced all-optical wavelength converter of 9.95328 Gbit/s 2.5 ps RZ-OOK signal is successfully demonstrated with power penalty < 0.5 dB over the maximal purup-probe wavelength spacing, similar to23 nm. It is implemented based on the cross-polarisation modulation (XPolM) effect in a 64 m-long nonlinear photonics crystal fibre (PCF). The Utilisation of such a short length of highly nonlinear PCF operating in the normal dispersion region not only reduces the wavelength converter's sensitivity to environmental disturbances and walk-off effect, but also eliminates modulation instability effects in the XPolM process.
