Multiple-channel output all-optical OTDM demultiplexer using XPM-induced chirp compensation (MOXIC)

The authors present a novel all-optical time-division demultiplexer capable of simultaneously outputting multiple channels at speeds of >100 Gbit/s. Its operation is based on time-wise local chirp compensation of a down-chirped clock pulse through cross-phase modulation (XPM) induced by a signal pulse stream. Error-free, simultaneous six-channel-output, 100 to 6.3 Gbit/s demultiplexing is successfully demonstrated.
