Abstract

Un segment de gaine en métal spécifique d'une espèce (18) sur un guide d'onde, y compris un guide d'ondes plat (12), permet une fuite régulée de lumière se propageant à travers le guide d'onde par réflexion interne totale, afin de mesurer l'indice de réfraction et d'identifier une espèce chimique. Un capteur à guide d'onde (10) est conçu pour une espèce chimique particulière par sélection d'une gaine en métal (18) présentant une affinité avec l'espèce, et par appariement des indices de réfraction du corps de guide d'onde, de la gaine, du segment de gaine en métal et de l'espèce chimique. Des procédés de mesure doubles ou multiples utilisent une paire de segments de gaine en métal multiples de spécificité différente. Le segment de gaine en métal (18) peut comprendre une autre matière afin d'offrir un indice de réfraction approprié, tout en ayant l'affinité voulue avec l'espèce chimique ou afin d'obtenir un catalyseur destiné à faire réagir l'espèce de manière à former un produit de réaction plus facilement détecté.
