The invention relates to a spectrograph () comprising a waveguide () provided with accesses (), 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 () for detecting the energy of the evanescent wave of the guided field produced by the interference of said contra-propagative waves.

Contra-propagative wave spectograph

An optoelectric device including a deformable membrane with an outer reflecting surface and an inner surface whereon a plurality of permanent magnets are fixed, and having a bottom surface entirely coated with a continuous layer of a flexible material; and a support including a plurality of electromagnets placed opposite the permanent magnets to exert an electromagnetic force thereon, locally displacing a zone corresponding to the deformable membrane.
