  • 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
    Filed: August 4, 2006
    Date of Patent: August 9, 2011
    Assignee: Universite Joseph Fourier
    Inventors: Etienne Le Coarer, Pierre Benech, Pierre Kern, Gilles Lerondel, Sylvain Blaize, Alain Morand
  • Deformable mirror
    Patent number: 7733550
    Abstract: 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.
