Abstract

We demonstrate all-optical demultiplexing of a high-bandwidth, time-division multiplexed $160\mathrm{Gbit}/\mathrm{s}$ signal to $10\mathrm{Gbit}/\mathrm{s}$ channels, exploiting slow light enhanced four-wave mixing in a dispersion engineered, $96\mathrm{\mu m}$ long planar photonic crystal waveguide. We report error-free (bit error rate$<{10}^{-9}$) operation of all 16 demultiplexed channels, with a power penalty of $2.2–2.4\mathrm{dB}$, highlighting the potential of these structures as a platform for ultracompact all-optical nonlinear processes.
