Multiple-channel output all-optical demultiplexer based on TDM-WDM conversion utilizing time-division chirping control of chirped clock pulse

We present a novel all-optical time-domain demultiplexer capable of simultaneously outputting multiple channels at speeds of over 100 Gbit/s. Its operation is based on time-division chirping control of a down-chirped clock pulse through cross-phase modulation (XPM) induced by a signal pulse stream.
