Abstract
(EN) An improved wavelength division multiplexing device (10) is disclosed. The improved wavelength division multiplexing device (10) monochromatic optical beams into a multiplexed, polychromatic optical beam. The improvement in the improved wavelength division multiplexo index collimating/focusing lens (16) for collimating the plurality of monochromatic optical beams (24) traveling along a first direction (24') to the diffraction grating (18), and for focusing the multiplexed, polychromatic optical beam (26) traveling along a second direction (26') from the diffraction grating (18) wherein the second direction (26') being substantially opposite the first direction (24').
(FR) L'invention concerne un dispositif de multiplexage par répartition en longueur d'onde amélioré (10). Le dispositif de multiplexage par répartition en longueur d'onde amélioré (10) diffuse l'optique monochromatique en un faisceau optique polychromatique multiplexé. L'amélioration de la lentille collimatrice/de focalisation d'indice (16) de multiplexage par répartition en longueur d'onde amélioré permettant de collimater les faisceaux optiques monochromatiques (24) se déplaçant dans une première direction (24') vers le réseau de diffraction (18), et de mettre au point le faisceau optique polychromatique multiplexé (26) se déplaçant dans une seconde direction (26') sensiblement opposée à la première (24').
