Abstract

L'invention porte sur des procédés et un appareil permettant d'appliquer une fonction prédéterminée de transfert spectral à valeur complexe sur un champ optique d'entrée de façon à générer un champ de sortie qui se propage dans une direction de sortie. L'invention porte également sur des procédés de fabrication de cet appareil. Des grilles fragmentées (1915, 1916, 19a15, 19a16) fabriquées conformément à un type de fabrication comprennent une série de sous-grilles distinctes spatiales mises en réseau bout à bout. Chaque sous-grille possède un ensemble périodique de structures de diffraction telles que des lignes ou autres éléments. On détermine les fonctions de transfert de ces grilles fragmentées en régulant (a) la périodicité ou fréquence spatiale de chaque sous-grille, (b) l'amplitude de chaque sous-grille, (c) l'espace entre la dernière structure de diffraction (ou ligne) sur chaque sous-grille et la première structure de diffraction (ou ligne) de la sous-grille successive, et (d) la longueur et la transparence du chemin optique dans chaque sous-grille, ou chaque sous-grille plus des couches de matériau additionnelles utilisées pour réguler la longueur et la transparence du chemin optique. L'invention porte également sur des système de communication utilisant ces grilles segmentées.
