description Disclosed herein is a holographic mixture including nanoparticles used to form gratings through holographic exposure. In various embodiments, exposure of the holographic mixture causes the nanoparticles to diffuse to dark fringe regions which creates nanoparticle rich regions and nanoparticle poor regions. Some embodiments include a multi-layer grating which includes a layer formed through the exposed holographic mixture and another layer directly applied above the exposed holographic mixture. The other layer may also be exposed through a holographic recording beam. L'invention concerne un mélange holographique comprenant des nanoparticules utilisées pour former des réseaux par exposition holographique. Dans divers modes de réalisation, l'exposition du mélange holographique amène les nanoparticules à se diffuser vers des régions de frange sombre, ce qui crée des régions riches en nanoparticules et des régions pauvres en nanoparticules. Certains modes de réalisation comprennent un réseau multicouche qui comprend une couche formée à travers le mélange holographique exposé et une autre couche directement appliquée au-dessus du mélange holographique exposé. L'autre couche peut également être exposée à travers un faisceau d'enregistrement holographique.
