Abstract

Dispositif de mesure d’une grandeur physique Ce dispositif de mesure comporte un étalon (6) dont le spectre de puissance en réflexion comporte plusieurs pics de puissance répartis à l’intérieur d’une plage de travail, l’intervalle spectrale libre de cet étalon étant inférieur ou égal à 5 nm, cet étalon comportant : - un guide d'onde (34), et - un réseau de Bragg (80) réalisé dans le guide d'onde, ce réseau de Bragg comportant au moins trois motifs identiques alignés les uns derrières les autres le long d’un axe longitudinal du guide d'onde et séparés les uns des autres par un pas constant. Le pas du réseau de Bragg (80) est configuré pour que son spectre de puissance présente plusieurs harmoniques discernables d’ordre supérieur à cent dans la plage de travail, ces harmoniques formant ainsi les pics de puissance du spectre de puissance de l’étalon.
