Demonstration of fibre four-wave mixing opticaldemultiplexingwith 19 dB parametric amplification

Abstract

An optical time-division demultiplexer with 19 dB conversion efficiency, using four-wave mixing at 1550 nm in a singlemode dispersion-shifted fibre, is presented. Eye patterns show successful demultiplexing from 20 Gbit/s to 10 Gbit/s.
