Abrégé
(EN)
Photopolymerizable materials and in particular holographic polymer dispersed liquid crystal materials and processes for fabricating holographic waveguide devices from such materials are provided. Materials and formulations of photopolymerizable materials are sufficiently low haze to allow for the omission of adhesives from within the cell of the holographic waveguide devices. The photopolymerizable materials are used in association with methods of manufacturing holographic waveguides such that photopolymerizable materials may be used as an adhesive material.

L'invention concerne des matériaux photopolymérisables et en particulier des matériaux à cristaux liquides dispersés dans un polymère holographique et des procédés de fabrication de dispositifs de guide d'ondes holographiques à partir de tels matériaux. Des matériaux et des formulations de matériaux photopolymérisables sont suffisamment faibles pour permettre l'omission d'adhésifs à partir de l'intérieur de la cellule des dispositifs de guide d'ondes holographiques. Les matériaux photopolymérisables sont utilisés en association avec des procédés de fabrication de guides d'ondes holographiques de telle sorte que des matériaux photopolymérisables puissent être utilisés en tant que matériau adhésif.
