Experimentally Verified Modelling of Parametric Amplification and Wavelength Conversion in Optical Fibres

We demonstrate parametric amplification of WDM signals and multiple wavelength conversion with gain based on four-photon parametric mixing in a highly nonlinear fibre (HNLF). Two pumps with a 100 GHz separation located in the region of anomalous dispersion of the HNLF are combined to form a beet signal. A high-power EDFA boosts the beet signal which is then combined with a signal wave by a directional coupler into the HNLF.
