Abstract

Une méthode de formage dun guide donde, la méthode comprenant les étapes de formage dun empilement multicouche de couches de guidage de lumière et la déstratification de lempilement multicouche à au moins deux des couches de guidage de lumière pour former un guide donde entre les couches de guidage de lumière, dans lesquelles la région du motif présente des côtés convergents et le guide donde est conique, lempilement multicouche ayant une transmissivité augmentée à une région correspondant à une épaisseur sélectionnée du guide donde. Un guide donde conique est également révélé, comprenant un empilement multicouche de couches de guidage; lempilement multicouche définissant un canal entre au moins une première couche de guidage de lumière et une deuxième couche de guidage de lumière; le canal présentant une épaisseur diminuant dans une première direction et au moins une de la première couche de guide donde et de la deuxième couche de guide donde comportant une région de transmission augmentée adjacente à une épaisseur sélectionnée du cur. Les méthodes dutilisation du guide donde conique comme coupleur optique ou spectromètre sont également révélées. Des méthodes visant lamélioration de la résolution optique du guide donde conique lorsquutilisé comme spectromètre sont également révélées.
