The invention relates to a spectrograph (11) comprising a waveguide (10) provided with accesses (10a, 10b, 12), a means for injecting two guided contra-propagative waves by each accesses in such a way that a spatial interference is formed in the waveguide, means (19, 20, 14, 16) for detecting the energy of the evanescent wave of the guided field produced by the interference of said contra-propagative waves.
La présente invention se rapporte à un spectrographe (11) comprenant un guide d'onde (10) muni de deux accès (10a, 10b, 12), un moyen d'injection de deux ondes guidées contra-propagatives par chacun desdits accès de sorte à créer une interférence spatiale au sein dudit guide, un moyen de détection (19, 20, 14, 16) de l'énergie de l'onde évanescente du champ guidé issu de l'interférence desdites ondes contra-propagatives.
