Scalable optical label generation and switching for packet routing in DWDM networks

We have experimentally demonstrated some key techniques in label switching optical networks. These techniques include optical label generation, optical label swapping and preamble free clock recovery. The label generation using optical carrier suppression and separation (OCSS) technique has these advantages of high bit rate operation, low cross-talk and narrow bandwidth occupancy. The label swapping is realized by combining OCSS and wavelength conversion. The payload can be simultaneously regenerated after wavelength conversion; hence this technique is very useful for cascaded label swapping in label switched optical networks. We have also demonstrated how to realize preamble free clock recovery for burst mode label and payload generated by OCSS technique.
