Abstract

Cette invention concerne un procédé de fabrication d'un guide d'onde optique, comprenant les étapes consistant à : (a) utiliser un film pour guide d'onde optique présentant des surfaces supérieure et inférieure permettant sensiblement la réflexion interne totale de la lumière entre celles-ci ; (b) appliquer un matériau visqueux et apte à subir un traitement thermique au moins à la surface inférieure selon un motif ; (c) faire subir audit matériau une texturation superficielle ; et (d) faire subir au matériau un traitement thermique. Le motif à texturation superficielle qui est ainsi formé sur la base du guide d'onde optique est apte à extraire de la lumière à partir du guide d'onde optique
