(JA) 光学部品用ポリイミド、光学部品および光導波路
Abstract: front page image
(EN)This invention provides a polyimide having very low transmission loss, an optical component, and an optical waveguide. The polyimide for an optical component is characterized in that it comprise at least diamines containing a diamine having a fluorine substituent and a fluorenyl group, and tetracarboxylic acid dianhydrides and the transmission loss at a wavelength of 830 nm is not more than 1 dB/cm in both TE mode and TM mode.
(FR)La présente invention concerne un polyimide présentant de très faibles pertes de transmission, un composant optique et un guide d’ondes optique. Le polyimide pour composant optique est caractérisé en ce qu’il comprend au moins des diamines contenant une diamine comportant un substituant fluor et un groupe fluorényle, et des dianhydrides d’acides tétracarboxyliques et en ce que la perte de transmission à une longueur d'ondes de 830 nm n'est pas supérieure à 1 dB/cm aussi bien en mode TE qu'en mode TM.
(JA) 本発明は、伝送損失の極めて低いポリイミド、光学部品および光導波路を提供することを目的とする。少なくともフッ素置換基及びフルオレニル基を有するジアミンを含むジアミン類とテトラカルボン酸二無水物類とを用いてなるポリイミドであって、波長830nmにおける伝送損失がTEモード、TMモードともに1dB/cm以下であることを特徴とする、光学部品用ポリイミドにより、伝送損失の極めて低いポリイミド、光学部品および光導波路により上記課題を解決しうる。
