Title (EN) OPTICAL WAVEGUIDE SUBSTRATE
(FR) SUBSTRAT DE GUIDE D'ONDE OPTIQUE
(JA) 光導波路基板
Abstract: front page image
(EN)This optical waveguide substrate (1) is provided with an optical waveguide (9) having an end face through which light enters and exits, the optical waveguide (9) being composed of a multilayered film (4) having a plurality of optical material films (5, 6). The end face is an etched surface, and concavities and convexities (7) produced by a difference in etching rate of the optical material films (5, 6) are provided to the end face.
(FR)L'invention concerne un substrat de guide d'onde optique (1) pourvu d'un guide d'onde optique (9) ayant une face d'extrémité à travers laquelle entre et sort la lumière, le guide d'onde optique (9) étant composé d'un film multicouche (4) ayant une pluralité de films en matériau optique (5, 6). La face d'extrémité est une surface gravée, et des concavités et des convexités (7) produites par une différente de vitesse de gravure des films en matériau optique (5, 6) sont situées sur la face d'extrémité.
(JA)光導波路基板1は、複数の光学材料膜5、6の多層膜4からなる光導波路9であって、光が入射または出射する端面を有する光導波路9を備える。端面がエッチング面であり、端面に光学材料膜5、6のエッチングレート差による凹凸7が設けられている。
