Novel all-optical wavelength converter based on self-pump four-wave mixing

A novel scheme of all-optical wavelength converter (AOWC) based on dual pump four-wave mixing (DP-FWM) was demonstrated. To suppress the ASE noise of the semiconductor optical amplifier (SOA), one of the two pumps was generated interiorly from a loop laser constructed mainly by tunable optical filter and SOA. The theoretical model and some experimental results were presented too.
