Optical Wavelength and Waveband Converters

FWM converter, a dual pump configuration should be used and (wavelength) down conversion is preferable. The fixed input signal wavelength should be close to the SOA band gap. This is a useful rule if the converter is to be used for a wavelengthrouted switch [7]. If the converter is combined with an arrayed waveguide grating
