    Device for locking the wavelength of an optical signal emitted by a source, comprising: a coupler (2) capable of extracting a fraction of the said optical signal, a splitter (4) capable of dividing the said fraction of the said optical signal into a first sub-fraction and a second sub-fraction, a first filter (FP1) capable of filtering the said first sub-fraction and of generating an optical signal when its wavelength is displaced to values below the wavelength of the optical signal to be locked, a second filter (FP2) capable of filtering the said second sub-fraction and of generating an optical signal when its wavelength is displaced to values above the wavelength of the optical signal to be locked, an opto-electronic device (6) capable of converting the said first filtered sub-fraction of the optical signal and the said second filtered sub-fraction of the optical signal, and of generating a signal corresponding to the said size of the displacement and a signal identifying the direction of the said displacement, both of which are to be used to adjust the emission spectrum of the said source.
