Abstract:
(EN)
An optical multiplexer (10) for multiplexing a plurality of light having different wavelengths, which is provided with: a first waveguide (101) on which light having a first wavelength is incident; a second waveguide (102) on which light having a second wavelength that is shorter than the first wavelength is incident; a third waveguide (103) on which light having a third wavelength that is shorter than the second wavelength is incident; a first multiplexing part (110) which propagates light between the first waveguide (101) and the second waveguide (102); and a second multiplexing part (120) which propagates light between the first waveguide (101) and the third waveguide (103). The light having the second wavelength is propagated to the first waveguide (101) by means of the first multiplexing part (110); and the light having the third wavelength is propagated to the first waveguide (101) by means of the second multiplexing part (120).

La présente invention concerne un multiplexeur optique (10) pour multiplexer une pluralité de lumières ayant différentes longueurs d’onde, qui est pourvu de : un premier guide d’ondes (101) sur lequel une lumière ayant une première longueur d’onde est incidente ; un deuxième guide d’ondes (102) sur lequel une lumière ayant une deuxième longueur d’onde qui est plus courte que la première longueur d’onde est incidente ; un troisième guide d’ondes (103) sur lequel une lumière ayant une troisième longueur d’onde qui est plus courte que la deuxième longueur d’onde est incidente ; une première partie de multiplexage (110) qui propage de la lumière entre le premier guide d’ondes (101) et le deuxième guide d’ondes (102) ; et une deuxième partie de multiplexage (120) qui propage de la lumière entre le premier guide d’ondes (101) et le troisième guide d’onde (103). La lumière ayant la deuxième longueur d’onde est propagée vers le premier guide d’ondes (101) au moyen de la première partie de multiplexage (110) ; et la lumière ayant la troisième longueur d’onde est propagée vers le premier guide d’ondes (101) au moyen de la deuxième partie de multiplexage (120).
(JA)
波長の異なる複数の光を合波する光合波器(10)であって、第1波長の光が入射される第1導波路(101)と、第1波長の光よりも短波長の第2波長の光が入射される第2導波路(102)と、第2波長の光よりも短波長の第3波長の光が入射される第3導波路(103)と、第1導波路(101)と第2導波路(102)との間で光を伝搬する第1合波部(110)と、第1導波路(101)と第3導波路(103)との間で光を伝搬する第2合波部(120)とを備え、第2波長の光は、第1合波部(110)で第1導波路(101)に伝搬され、第3波長の光は、第2合波部(120)で第1導波路(101)に伝搬される。
