An improved integrated optic interferometric sensor uses a planar waveguide to offer detection sensitivity equal to the Mach-Zehnder interferometric sensor, while retaining the input coupling and manufacturing ease characteristic of a planar waveguide. Enhanced output signal processing capabilities are provided by use of at least two integrated optic interferometric sensors employing planar constructs.

L'invention concerne un capteur interférométrique optique intégral amélioré utilisant un guide d'ondes planaire, de façon à offrir une sensibilité de détection égale au capteur interférométrique Mach-Zehnder, tout en gardant le couplage d'entrée et la facilité de fabrication caractéristiques d'un guide d'ondes planaire. Les capacités de traitement des signaux de sortie sont plus importantes du fait de l'utilisation d'au moins deux capteurs interférométriques optiques intégraux utilisant des constructions planaires.
