Abstract:
(EN) A laser device (1) is provided with: a branching waveguide (23) that outputs a plurality of light beams by branching propagation light into a plurality of light beams, said propagation light having been propagated from an optical amplifier (10); a multicore waveguide (27) having a plurality of waveguide cores (24-26) that respectively propagate the light beams inputted from the branching waveguide (23); and a light reflector (31) optically coupled to a light input/output end of the multicore waveguide (27). The waveguide cores (24-26) extend in the same direction, and are disposed close to each other so that the waveguide cores adjacent to each other among the waveguide cores (24-26) are optically coupled to each other.
(FR) Selon l'invention, un dispositif laser (1) comprend : un guide d'ondes de ramification (23) qui émet une pluralité de faisceaux lumineux par ramification de la lumière de propagation en une pluralité de faisceaux lumineux, ladite lumière de propagation ayant été propagée à partir d'un amplificateur optique (10) ; un guide d'ondes multicœur (27) ayant une pluralité de cœurs de guide d'ondes (24-26) qui propagent respectivement les faisceaux lumineux entrés à partir du guide d'ondes de ramification (23) ; et un réflecteur de lumière (31) optiquement couplé à une extrémité d'entrée/sortie de lumière du guide d'ondes multicœur (27). Les cœurs de guide d'ondes (24-26) s'étendent dans la même direction, et sont disposés à proximité les uns des autres de telle sorte que les cœurs de guide d'ondes adjacents les uns aux autres parmi les cœurs de guide d'ondes (24-26) sont couplés optiquement les uns aux autres.
(JA) レーザ装置(1)は、光増幅器(10)からの伝搬光を複数本の光に分岐させて当該複数本の光を出力する分岐導波路(23)と、分岐導波路(23)から入力された当該複数本の光をそれぞれ伝搬させる複数の導波路コア(24~26)を有するマルチコア導波路(27)と、マルチコア導波路(27)の光入出力端と光学的に結合された光反射器(31)とを備える。導波路コア(24~26)は、同一方向に沿って延在し、かつ当該導波路コア(24~26)のうち隣り合う導波路コア同士が光学的に結合するように、互いに近接して配置されている。
