Abstract

Abstract Translated from Japanese (57)【要約】 【構成】基板1上に、有機材料からなるコア4と、該コ ア4を挾持するようその上下に形成されたクラッド層 3,5を有し、前記コア4および上下クラッド層3,5 に電界を印加する一対の電極2,6を備えた導波路型光 変調素子であって、前記コアに接する上部クラッド層6 の少なくとも電界の及ぶ部分が、電気光学効果を有する 高分子材料により構成されていることを特徴とする導波 路型光変調素子。 【効果】ポリイミドをベースとした非線形光学高分子材 料を電気光学素子に適用することが可能となり、優れた 耐熱性、低損失、高性能指数の光スイッチが実現でき る。 (57) [Summary] [Structure] On a substrate 1, a core 4 made of an organic material and clad layers 3 and 5 formed above and below so as to hold the core 4 are provided. Layers 3, 5 A waveguide-type optical modulator including a pair of electrodes 2 and 6 for applying an electric field to the upper clad layer 6 in contact with the core. A waveguide-type optical modulation element, characterized in that at least a portion to which an electric field is applied is made of a polymer material having an electro-optical effect. [Effect] A non-linear optical polymer material based on polyimide can be applied to an electro-optical element, and an optical switch having excellent heat resistance, low loss, and high performance index can be realized.
