Title (EN) PHOTONIC INTEGRATED CIRCUITS AND DEVICES FOR PHOTONIC SENSING
(FR) CIRCUITS INTÉGRÉS PHOTONIQUES ET DISPOSITIFS DE DÉTECTION PHOTONIQUE
Abstract: front page image
(EN) A photonic sensing system includes an interrogator coupled to a sensing fiber. The interrogator includes a light source (44) configured to emit light, and a photonic integrated circuit (48) comprising a plurality of photonic components like polarisation rotatot (58), circulator (64), splitter (68), edge coupler (62, 40), waveguides (66, 70, 72) and photodiodes (74, 80, 82). The PIC is configured to transmit the light emitted by the light source and to receive reflected light from the sensing fiber. The interrogator also includes a plurality of integrated circuit (86, 88, 90, 92, 94, 96) components configured to process and analyze signals from the interrogator to determine one or more measurands like current flowing through an electrical conductor around which the sensing fibre is coiled.
(FR) Cette invention concerne un système de détection photonique comprenant un interrogateur couplé à une fibre de détection. L'interrogateur comprend une source de lumière configurée pour émettre de la lumière, et un circuit intégré photonique (CIP) comprenant une pluralité de composants photoniques. Le circuit intégré photonique est configuré pour transmettre la lumière émise par la source de lumière et pour recevoir la lumière réfléchie provenant de la fibre de détection. L'interrogateur comprend également une pluralité de composants de circuit intégré (CI) configurés pour traiter et analyser des signaux provenant de l'interrogateur pour déterminer une ou plusieurs grandeurs à mesurer.
