    Abstract: Two grooves (10) are dice-cut along a light passing direction in a crystal dummy phase matching element (1) to thereby form a protrusion (11), held between the two grooves (10), on the upper surface side in Figures as shown in Figs. 4 (b), (c); and a ridge type waveguide (9) is formed within the protrusion. When light is allowed to pass through the waveguide (9), the light passes through a crystal axis reversal portion (polarization reversal region) (4) while being confined in the waveguide (9) to undergo wavelength conversion. A light energy can be kept high within a wavelength conversion element to ensure a high wavelength conversion efficiency.

    Abstract: Une structure guidante (16, 18, 20, 22) de ce composant inclut une structure de coeur (18) s'étendant jusqu'à des faces de couplage (8, 10). Elle comporte au moins trois couches à haut indice (30, 34, 38) présentant des indices de réfraction accrus par rapport aux milieux environnants (16, 32, 36, 20) pour augmenter dans ces couches la densité de puissance d'une lumière devant subir un traitement tel qu'une modulation d'amplitude. Ces couches à haut indice ont des compositions leur permettant de réaliser ce traitement en réponse à une excitation électrique tout en ayant des épaisseurs supérieures à celles de puits quantiques. Elles sont séparées par des couches de dilution (32, 36) à indice de réfraction plus faible et à épaisseurs plus grandes telles qu'un seul mode de propagation de la lumière soit guidé par la structure guidante. Ce mode présente une épaisseur adaptée à un couplage à un élément optique externe tout en confinant une majorité de la puissance de la lumière dans l'épaisseur de la structure de coeur pour favoriser le traitement.
