Zusammenfassung:Many applications require the use of lasers with short optical ray lengths. However, at present, there is no module that makes it possible to refine a ray from a light source in a satisfactory manner, in particular one from a semiconductor laser. The invention relates to a spectral refinement method (500), a device with refined spectral line (200) comprising at least one light source (210) and a spectral refinement module (100). The latter includes at least one first coupler (111), a Brillouin resonator (120) and a modulator (130).
