Title (EN) NON-UNIFORM GRATING
(FR) RÉSEAU NON UNIFORME
Abstract: front page image
(EN)A system includes a non-uniform grating (100) having a first region (110) with a first refractive index and second regions (120) with a second refractive index. A pattern of the second regions (120) varies with an angular coordinate such that phase shifts of an incident beam (130) created by the grating (100) cause destructive interference that creates an intensity minimum within an output beam (134) from the grating (100).
(FR)L'invention concerne un système comprenant un réseau non uniforme (100) ayant une première région (110) avec un premier indice de réfraction et des deuxièmes régions (120) avec un deuxième indice de réfraction. Le motif des deuxièmes régions (120) varie avec les coordonnées angulaires de telle sorte que les déphasages d'un faisceau incident (130) créés par le réseau (100) induisent des interférences destructives qui se traduisent par un minimum d'intensité à l'intérieur du faisceau de sortie (134) du réseau (100).
