The noise figure of an optical frequency converter based on four-wave mixing in a semiconductor optical amplifier is defined and measured. The noise figure of the frequency converter is shown to be a function of the optical pump power, and is reduced at pump levels which are higher than the pump power required for maximum conversion efficiency.
