Abstract

A 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 pump-probe wavelength spacing, /spl sim/23 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.
