Abstract
A wavelength converter is disclosed. The converter comprises a broadband light source producing light having a plurality of wavelengths. Further, a semiconductor optical amplifier is provided that receives the light from the light source. The semiconductor optical amplifier amplifies the light under the control of a control signal related to an optical signal of a first wavelength. Next, a demultiplexer receives the output of the semiconductor optical amplifier and extracts from the amplified optical signal at least one of the plurality of wavelengths.
