Abstract:
(EN) An optical element (4) is provided with: a silicon waveguide core (1) that is provided with a taper section (1X) having the cross-sectional size reduced toward the terminal portion thereof; a dielectric waveguide core (2), which is connected to the silicon waveguide core by covering at least the taper section, and which has a refractive index smaller than that of the silicon waveguide core, and which constitutes a single-mode waveguide; and a diffraction grating (3), which is provided in the single-mode waveguide, and which constitutes a distributed Bragg reflector.
(FR) La présente invention porte sur un élément optique (4) qui comporte : un cœur de guide d'onde de silicium (1) qui comporte une section effilée (1X) ayant la dimension de section transversale réduite vers la partie terminale de celui-ci ; un cœur de guide d'onde diélectrique (2), qui est relié au cœur de guide d'onde de silicium par couverture d'au moins la section effilée et qui a un indice de réfraction inférieur à celui du cœur de guide d'onde de silicium, et qui constitue un guide d'onde monomode ; et un réseau de diffraction (3), qui est disposé dans le guide d'onde monomode et qui constitue un réflecteur de Bragg réparti.
(JA)  光素子(4)を、終端部へ向けて断面サイズが小さくなるテーパ部(1X)を備えるシリコン導波路コア(1)と、少なくともテーパ部を覆ってシリコン導波路コアに連なり、シリコン導波路コアよりも小さい屈折率を有し、単一モード導波路を構成する誘電体導波路コア(2)と、単一モード導波路に設けられ、分布ブラッグ反射鏡を構成する回折格子(3)とを備えるものとする。
