Abstract:
(EN) An optical element (501) includes a plurality of optical filters having different characteristics. The element includes a first optical filter (505) including a first metal structure group (503) including first metal structures periodically arranged in an in-plane direction of a substrate (502) surface and a second optical filter (506) including a second metal structure group (504) including second metal structures periodically arranged in the in-plane direction, the second metal structure group exhibiting a plasmon resonance condition different from that of the first metal structure group. The optical distance (507) between the first metal structures adjacent to each other is in a range of 0.75 to 1.25 times the optical distance (507) between the second metal structures adjacent to each other.
(FR) On décrit un élément optique (501) comprenant une pluralité de filtres optiques présentant des caractéristiques différentes. L'élément comprend un premier filtre optique (505) comportant un premier groupe (503) de structures métalliques comprenant des premières structures métalliques disposées périodiquement dans une direction interne au plan de la surface d'un substrat (502) et un deuxième filtre optique (506) comportant un deuxième groupe (504) de structures métalliques comprenant des deuxièmes structures métalliques disposées périodiquement dans la direction interne au plan, le deuxième groupe de structures métalliques présentant un état de résonance des plasmons différent de celui du premier groupe de structures métalliques. La distance optique (507) entre les premières structures métalliques adjacentes les unes aux autres se situe dans un intervalle de 0,75 à 1,25 fois la distance optique (507) entre les deuxièmes structures métalliques adjacentes les unes aux autres.
