Title
(EN) SENSOR WITH A MICROSTRUCTURED FIBER OPTIC BASE AND BRAGG NETWORK
(FR) CAPTEUR A BASE DE FIBRE OPTIQUE MICROSTRUCTUREE ET A RESEAU DE BRAGG
Abstract
(EN)
The invention involves a sensor (100) with a Bragg network fiber including a source (105) and detection system (101) operating at a wavelength of a given study, in addition to a Bragg (6) network fiber (1) linked to said source and said system, with said fiber being a microstructured optic fiber whose sheath (5) includes channels (3) adjacent to the heart (2) of the fiber (1), capable of receiving a product to be analyzed, characterized in that the number of channels (3) adjacent to the heart (2) is between 2 and 5, and that the size of the heart (2) of the fiber (1) is adapted so that an electromagnetic field of a wave guided by the fiber is not confined in the heart (2) of the fiber (1), and the electromagnetic field extends into the channels (3).
(FR)
L'invention concerne un capteur (100) à fibre à réseau de Bragg comportant une source (105) et un système de détection (101) fonctionnant à une longueur d'onde d'étude donnée, ainsi qu'une fibre (1) à réseau de Bragg (6) reliée à ladite source et au dit système, ladite fibre étant une fibre optique microstructurée dont la gaine (5) comprend des canaux (3) adjacents au cœur (2) de la fibre (1), aptes à recevoir un produit à analyser, caractérisé en ce que le nombre de canaux (3) adjacents au cœur (2) est compris entre 2 et 5, et en ce que le diamètre du cœur (2) de la fibre (1) est adapté pour qu'un champ électromagnétique d'une onde guidée par la fibre ne soit pas confiné dans le cœur (2) de la fibre (1), le champ électromagnétique s'étendant dans les canaux (3).
