Abstract

Linvention concerne la fabrication de nanostructures périodiques à grande portée de haute qualité, dans un substrat transparent ou semi-transparent, ledit substrat transparent ou semi-transparent étant balayé par un faisceau laser polarisé de façon linéaire généré par un laser femtoseconde et dépassant un seuil prédéterminé dénergie ou dimpulsion sur un tracé de balayage. Des structures limites de sous-diffraction sont formées à titre de plans périodiques de matière modifiée, dans le substrat transparent ou semi-transparent sétendant le long du tracé de balayage. La matière modifiée peut ensuite être moulée chimiquement pour former des cavités.
