SPECTRAL REFINEMENT MODULE, DEVICE WITH REFINED SPECTRAL LINE AND ASSOCIATED METHOD

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). 本发明涉及光谱窄化模块、细化光谱线装置及其相关联的方法。许多应用要求使用具有短光学射线长度的激光器。然而，目前，没有模块能够以令人满意的方式细化来自光源的光线，特别是来自半导体激光器的光线。本发明涉及光谱细化方法(500)，具有细化光谱线(200)的装置，该装置包括至少个光源(210)和光谱细化模块(100)。光谱细化模块(100)包括至少个第耦合器(111)、布里渊谐振器(120)和调制器(130)。
