Error-free all-optical demultiplexing at 160Gb/s via FWM in a silicon nanowire

We demonstrate all-optical time division demultiplexing from 160Gb/s to 10Gb/s in the C-band, based on four-wave mixing (FWM) in a silicon nanowire. We achieve error-free operation with a system penalty of ~3.9dB at 10 -9 BER.
