ABSTRACT OF THE DISCLOSURE Integrated monomode spatial optical filter and its method of embodiment. The optical filter of the invention for isolating one first optical mode and eliminating second stray optical modes consists of an optical microguide (9) borne by a substrate (2) and having along a plane parallel to the surface (P) of the substrate at least one curved portion (6) whose radius of curvature is such that the losses in the curve of the first and second modes are respectively negligible and extremely high and two light absorbers (8, 10) disposed within a given plane on both sides of the curved portion (6).
