Abstract
The invention relates to a spectrograph (11) comprising a waveguide (10) provided with accesses (10; 10 b , 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.
