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.
