Multiple-output, 100 Gbit/s all-optical demultiplexerbased on multichannel four-wave mixingpumped by a linearly-chirped square pulse

A novel ultrafast multiple-output all-optical time-domain demultiplexer is proposed based on multiwavelength-channel four-wave mixing with a linearly-chirped supercontinuum square pump pulse. Error-free, simultaneous four-output, 100 Gbit/s to 6.3 Gbit/s demultiplexing of a 0.42 ps signal pulse train has been demonstrated for the first time.
