Title (EN) OPTICAL WAVEGUIDE ELEMENT
(FR) ÉLÉMENT DE GUIDE D’ONDES OPTIQUES
(JA) 光導波路素子
Abstract:
(EN) An optical waveguide element is provided with: a cladding part formed on a substrate; an optical waveguide formed in the cladding part, the optical waveguide having a refractive index higher than that of the cladding part; an optical filter inserted into a slit formed in the cladding part so as to divide the optical waveguide into a first optical waveguide and a second optical waveguide; and at least one thin film element inserted with the optical filter into the slit, the thin film element being provided with a thin film lens, the thin film lens provided to one of the thin film elements causing light that has been propagated through the first optical waveguide and outputted into the slit to converge onto the second optical waveguide.
(FR) La présente invention a trait à un élément de guide d'ondes optiques, lequel est pourvu : d'une partie de revêtement formée sur un substrat ; d'un guide d'ondes optiques formé dans la partie de revêtement, le guide d'ondes optiques présentant un indice de réfraction supérieur à celui de la partie de revêtement ; un filtre optique introduit dans une fente formée dans la partie de revêtement de manière à diviser le guide d'ondes optiques en un premier guide d'ondes optiques et en un second guide d'ondes optiques ; et au moins un élément à film mince introduit avec le filtre optique dans la fente, l'élément à film mince étant pourvu d'une lentille à film mince, la lentille à film mince dotant l'un des éléments à film mince amenant la lumière qui s'est propagée à travers le premier guide d'ondes optiques et émise dans la fente à converger sur le second guide d'ondes optiques.
(JA) 光導波路素子は、基板上に形成されたクラッド部と、前記クラッド部内に形成され、前記クラッド部よりも屈折率が高い光導波路と、前記光導波路を第1光導波路と第2光導波路とに分断するように前記クラッド部に形成されたスリットに挿入された光学フィルタと、前記光学フィルタとともに前記スリットに挿入され、薄膜レンズが設けられた少なくとも1つの薄膜素子と、を備え、前記薄膜素子の1つに設けられた薄膜レンズは、前記第1光導波路を伝搬し前記スリット内に出力された光を、前記第2光導波路に集光させる。
