The present invention relates to an optical fiber and a planar waveguide for achieving a uniform optical attenuation, which comprises a core co-doped with a first metal ions having an optical absorption coefficient of a negative slope in a particular wavelength band and a second metal ions having an optical absorption coefficient of a positive slope in a predetermined wavelength band.
L'invention porte sur une fibre optique et un guide d'ondes planaire permettant d'obtenir une atténuation optique uniforme. Cette fibre optique et ce guide d'ondes planaire comprennent une âme co-dopée à des premiers ions métalliques présentant un coefficient d'absorption optique de pente négative sur une bande de longueur d'ondes particulière, et à des deuxièmes ions métalliques présentant un coefficient d'absorption optique de pente positive sur une bande de longueur d'ondes prédéterminée.
