Polarisation-independent all-optical demultiplexingup to 200 Gbit/s using four-wave mixingin a semiconductor laser amplifier

Abstract

Polarisation-independent all-optical time-division demultiplexing is demonstrated up to 200 Gbit/s with <0.5 dB polarisation dependency based on four-wave mixing in depolarised TE and TM modes in a travelling-wave semiconductor laser amplifier.
