Abstract
An integrated interferometer structure, in particular for optical signal wavelength converters, includes a first branch and a second branch including at least a first semiconductor optical amplifier coupled to input and/or output peripheral semiconductor optical amplifiers. The structure includes an attenuation section between the output of at least one amplifier of one branch and the input of the output peripheral amplifier and/or the length of the waveguide of at least one peripheral amplifier is less than 300 .mu.m. Applications in telecommunications, in particular for routing signals.
