The invention relates to a wavelength converter including an interferometer structure for delivering an output optical signal, in which converter a first branch contains a first semiconductor optical amplifier and a second branch contains a second semiconductor optical amplifier, the amplifiers being coupled to a common probe laser, and said first amplifier being organized to receive a modulating input signal, said converter including regulator means for acting on the total optical power delivered to said amplifier in response to a negative feedback signal representative of the extinction ratio of the output signal. The invention is applicable to making routing systems using wavelength-division multiplexing.
