Title (EN) GRATING IN A HIGH INDEX CONTRAST STRIP OR CHANNEL WAVEGUIDE AND METHOD OF FORMING THE SAME
(FR) GRILLE DANS UN GUIDE D'ONDE DE CANAL OU UNE BANDE DE CONTRASTE A INDICE ELEVE ET SON PROCEDE D'ELABORATION
Abstract: front page image
(EN) A high index difference coupler (2, 14) includes a high index difference waveguide (3, 15) having one or more modes. A plurality of gratings (6, 16) is formed on the high index difference waveguide. The effective index difference between low index regions and high index regions of the waveguide is greater than 0.3.
(FR) L'invention concerne un coupleur de différences d'indices élevés (2, 14) comprenant un guide d'onde de différence d'indices élevés (3, 15) possédant au moins un mode. Une pluralité de grilles (6, 16) est formée sur le guide d'onde de différence d'indices élevés. La différence d'indices efficaces entre des zones d'indices faibles et des zones d'indices élevés du guide d'onde est supérieure à 0,3.
