Patent

CA 2443129

The invention features high index-contrast fiber waveguides (1301) that can be drawn from a preform. The invention also features materials for forming high index-contrast fiber waveguides (1301), and guidelines for their selection. High index-contrast fiber waveguides (1301), which may include opical fibers and photonic crystal fibers, can provide enhanced radial confinement of an optical signal in the fiber waveguide (1301). Moreover, large optical energy densities can be achieved inside the high index-contrast fiber waveguides, making them attractive candidates for a number of applications.

L'invention concerne des guides d'ondes de fibres à contraste d'indice élevé (1301) pouvant provenir d'une préforme. L'invention concerne également des matériaux destinés à former des guides d'ondes à fibres à contraste d'indice élevé (1301) et des directives destinées à leur sélection. Ces guides d'ondes à fibres à contraste d'indice élevé (1301), pouvant comprendre des fibres optiques et des fibres cristallines photoniques, peuvent produire un confinement radial amélioré d'un signal optique dans le guide d'ondes à fibres (1301). En outre, de grandes densités d'énergie optique peuvent être atteintes à l'intérieur des guides d'ondes à fibres à contraste d'indice élevé, les transformant en candidats intéressants pour un certain nombre d'applications.
