Title (EN) OPTICAL FILTER
(FR) FILTRE OPTIQUE
Abstract: front page image
(EN)The present invention provides an optical filter, for use in a range of devices, in which two or more multimode waveguides are combined into a single filter. The filter can be designed to achieve many different transmission characteristics by adapting the physical characteristics (such as length, width, or height) and/or number of multimode waveguides.
(FR)La présente invention se rapporte à un filtre optique qui est destiné à être utilisé dans divers dispositifs et dans lequel deux guides d'ondes multimodes ou plus sont combinés pour former un seul filtre. Ledit filtre peut être conçu pour présenter de nombreuses caractéristiques de transmission différentes grâce à l'adaptation des caractéristiques physiques (telles que la longueur, la largeur ou la hauteur) et/ou du nombre de guides d'ondes multimodes.
