成功地实现了一种可调谐的、稳定性增强的全光波长转换器，输出信号为9.95328Gbit/s2.5ps的RZ OOK信号，在最大泵浦-探测波长间隔为1.23nm时，功率损失<0.5dB。它是基于64 m长的非线性光子晶体光纤（PCF）中的交叉偏振调制（XPolM）效应实现的。利用在正常色散区域中操作的这种短长度的高度非线性PCF不仅降低了波长转换器对环境干扰和走离效应的敏感性，而且消除了XPolM过程中的调制不稳定性效应。
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, ∼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.
