Abstract :
Asynchronous all-optical bit-by-bit self-signal recognition and simultaneous demultiplexing based on intensity-dependent self-frequency shift induced by Raman soliton effect is demonstrated. Better than 3 dB recognition sensitivity, faster than 640 Gbit/s demultiplexing and capability of three-times cascade operation are confirmed.
