  • Contra-propagative wave spectograph
    Patent number: 7995211
    Abstract: The invention relates to a spectrograph (11) comprising a waveguide (10) provided with accesses (10; 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.
    Type: Grant

  • Hybrid integrated electro-optical modulator of the pockels effect type
    Patent number: 6185033
    Abstract: A Pockels-effect electro-optical modulator including a light guide having a core made of an inorganic amorphous material, and on which a structure is superposed that is made up of two electrode-forming layers between which an electro-optical polymer is interposed, said modulator being characterized in that said structure is superposed directly on the material of the core of the light guide. The transitions between the active and passive zones are advantageously adapted to minimize losses.
