Title (EN) OPTICAL WAVEGUIDE ELEMENT AND LIGHT SOURCE MODULE
(FR) ÉLÉMENT GUIDE D'ONDES OPTIQUE ET MODULE DE SOURCE DE LUMIÈRE
(JA) 光導波路素子及び光源モジュール
Abstract:
(EN) An optical waveguide element (13) that guides at least three light beams having different wavelengths is provided with: a substrate (15); a plurality of cores (11B, 11R, 11G) that guide the light beams, respectively; and a cladding (17) surrounding around the cores (11B, 11R, 11G). The optical waveguide element has an input end surface (13a) to which the light beams are inputted, and an output end surface (13b) from which the light beams are outputted, and the cores (11B, 11R, 11G) are formed by being separated from each other. Each of the center-to-center distances of the cores (11B, 11R, 11G) on the output end surface (13b) is smaller than each of the center-to-center distances of the cores (11B, 11R, 11G) on the input end surface (13a).
(FR) L'invention concerne un élément guide d'ondes optique (13) qui guide au moins trois faisceaux lumineux ayant différentes longueurs d'onde, et qui comprend : un substrat (15) ; une pluralité de noyaux (11B, 11R, 11G) qui guident les faisceaux lumineux, respectivement ; et une gaine (17) entourant les noyaux (11B, 11R, 11G). L'élément guide d'ondes optique a une surface d'extrémité d'entrée (13a) dans laquelle les faisceaux lumineux sont entrés, et une surface d'extrémité de sortie (13b) à partir de laquelle les faisceaux lumineux sont délivrés en sortie, et les noyaux (11B, 11R, 11G) sont formées en étant séparées les unes des autres. Chacune des distances centre à centre des noyaux (11B, 11R, 11G) sur la surface d'extrémité de sortie (13b) est inférieure à chacune des distances centre à centre des noyaux (11B, 11R, 11G) sur la surface d'extrémité d'entrée (13a).
(JA) 少なくとも3つの波長が異なる複数の光を導波する光導波路素子(13)であって、基板(15)と、複数の光をそれぞれ導波する複数のコア(11B,11R,11G)と、コア(11B,11R,11G)の周囲を囲むクラッド(17)を備え、複数の光が入射される入射端面(13a)と、複数の光が出射される出射端面(13b)を有し、複数のコア(11B,11R,11G)は互いに離間して形成されており、入射端面(13a)での複数のコア(11B,11R,11G)同士の中心間距離よりも、出射端面(13b)での複数のコア同士の中心間距離の方が小さい。
