Abstract

De faibles pertes de connexion et une efficacité d'opération élevée peuvent être obtenues en diminuant la section transversale de guide d'ondes d'une partie de commande de la lumière, cette partie étant un élément d'un guide d'ondes optique, et en augmentant relativement la taille de point lumineux du faisceau lumineux guidé au niveau de la partie de commande de la lumière. Selon cette invention, les dimensions d'une partie d'entrée de la lumière (22), d'une partie de commande de la lumière (24) et d'une partie de sortie de la lumière (26) satisfont les conditions de mode unique. Du moins, la relation entre les largeurs W1, W2, et W3 respectivement de la partie d'entrée de la lumière (22), de la partie de commande de la lumière (24) et de la partie de sortie de la lumière (26) est exprimée par les inéquations W2<W1 et W2<W3, et la relation entre les épaisseurs T1, T2, et T3 respectivement de la partie d'entrée de la lumière (22), de la partie de commande de la lumière (24) et de la partie de sortie de la lumière (26) est exprimée par les inéquations T2<T1 et T2<T3.
