Title (EN) DYNAMICALLY RECONFIGURABLE HOLOGRAMS WITH CHALCOGENIDE INTERMEDIATE LAYERS
(FR) HOLOGRAMMES RECONFIGURABLES DYNAMIQUEMENT AVEC COUCHES INTERMÉDIAIRES AU CHALCOGÉNURE
Abstract:
(EN) Various embodiments of the present invention relate to dynamically reconfigurable hologram comprising a phase-modulation layer and an intensity-control layer. The phase modulation layer comprises an electronically programmable erasable negative index material crossbar. The crossbar includes a first layer of approximately parallel nanowires (502) and a second layer of approximately parallel nanowires (504) that overlay the nanowires in the first layer. The nanowires in the first and second layers have substantially regularly spaced fingers. The crossbar also includes resonant elements (812) comprising a chalcogenide-based layer (1000) sandwiched between the nanowire in the first layer and the nanowire in the second layer.
(FR) Divers modes de réalisation de la présente invention concernent des hologrammes reconfigurables dynamiquement comprenant une couche de modulation de phase et une couche de contrôle d'intensité. La couche de modulation de phase comprend un réseau matriciel en matériau à indice négatif effaçable électroniquement programmable. Le réseau matriciel comprend une première couche de nanofils approximativement parallèles (502) et une seconde couche de nanofils approximativement parallèles (504) qui chevauchent les nanofils de la première couche. Les nanofils dans les première et seconde couches comportent des contacts espacés sensiblement régulièrement. Le réseau matriciel comprend aussi des éléments résonnants (812) comprenant une couche à base de chalcogénure (1000) intercalée entre le nanofil de la première couche et le nanofil de la seconde couche.
