Zusammenfassung:To provide a device for combining several light beams.SOLUTION: A device (1) for combining several light beams includes several hollow input waveguides (21, 22, 23), at least one per light beam, as well as a hollow output waveguide (40) which is the same for the different light beams. Each input waveguide has an input opening (24, 26, 28) to let the corresponding light beam enter, and, on the opposite side, an output opening (25, 27, 29) through which the light beam emerges in the output waveguide. The output waveguide, as well as each input waveguide, is laterally delimited by one or more metallic reflecting surfaces (46, 47, 48, 49). At least a section (42) of the output waveguide (40) is divergent and widens in the direction of an output opening (45) of the output waveguide.SELECTED DRAWING: Figure 2 【課題】いくつかの光ビームを結合するためのデバイスを提供すること【解決手段】いくつかの光ビームを結合するデバイス(1)は、光ビームごとに少なくとも1つの、いくつかの中空の入力導波路(21、22、23)と、異なる光ビームに対して同一である中空の出力導波路(40)とを含み、各入力導波路が、対応する光ビームを入射させる入力開口(24、26、28)と、その反対側に、出力開口(25、27、29)とを有し、この出力開口を通して出力導波路に光ビームを出し、出力導波路は、各入力導波路と同様に、1つ以上の金属反射面(46、47、48、49)によって横方向に区切られており、出力導波路(40)の少なくとも一部分(42)は発散し、出力導波路の出力開口(45)の方向に広がっている。【選択図】図2
