Title (EN) OPTICAL DEVICE CAPABLE OF PROVIDING AT LEAST TWO DIFFERENT OPTICAL FUNCTIONS
(FR) DISPOSITIF OPTIQUE PERMETTANT DE FOURNIR AU MOINS DEUX FONCTIONS OPTIQUES DIFFÉRENTES
Abstract:
(EN) An optical device forming an outgoing electromagnetic wave from an incident electromagnetic wave comprises at least one unit cell (UC), comprising: at least two subwavelength optical elements (1, 2), each of them belonging to a different set (MSI, MS2) of subwavelength optical elements, a set of subwavelength optical elements being characterized by a type of optical response to an incident electromagnetic wave; means (21) enabling selective excitation of all subwavelength optical elements belonging to a given set, in response to an electromagnetic wave (20) incident on said unit cell.
(FR) La présente invention concerne un dispositif optique formant une onde électromagnétique de sortie à partir d’une onde électromagnétique incidente qui comprend au moins une cellule unitaire (UC), comprenant : au moins deux éléments optiques de sous-longueur d’onde (1, 2), chacun d’eux appartenant à un ensemble différent (MSI, MS2) d’éléments optiques de sous-longueur d’onde, un ensemble d’éléments optiques de sous-longueur d’onde étant caractérisé par un type de réponse optique à une onde électromagnétique incidente ; des moyens (21) permettant l’excitation sélective de tous les éléments optiques de sous-longueur d’onde appartenant à un ensemble donné, en réponse à une onde électromagnétique (20) incidente sur ladite cellule unitaire.
