  • Patent number: 9547367
    Abstract: The The invention relates to a touch interface comprising a contact surface and means for vibrating the contact surface, said means being provided to generate standing waves in said surface. The contact surface includes at least one transparent portion forming a surface for seeing through the touch interface, and the vibration generating means include at least one rigid piezoelectric layer that is rigidly connected to the contact surface and disposed on the periphery of the transparent portion. The interface is characterized in that the at least one piezoelectric layer is disposed in a plane that is not parallel to the contact surface. The invention also relates to a display screen using such an interface, and to an electric appliance using such a display screen.

  • Patent number: 9488780
    Abstract: A device for converting transverse spatial profile of intensity of a light beam, using a microstructured optical fiber. Transverse dimensions of the fiber vary longitudinally and both its ends have opto-geometrical parameters such that at the wavelength of the beam the fiber has a fundamental mode having two different profile shapes at its two ends. Thus by introducing the beam with one of the profiles through one of the two ends, the beam emerges through the other end with the other profile, whose shape is different from that of the profile of the introduced beam.

  • Patent number: 9250497
    Abstract: Method and device for the optical parametric chirped pulse amplification, using two pump signals and making it possible to extend the spectral gain band. According to the invention, which is particularly applicable to laser-matter interaction, a four-wave mixing effect is used, preferably in an optical fiber (F), between each pulse (S) and the two pump signals (P1, P2); and the half-sum (fM) of the respective optical frequencies (fP1, fP2) of these signals pertains to the pulse spectrum support.

  • Patent number: 9244219
    Abstract: The fiber comprises a core (2) having an index N and diameter of 10 ?m or more, surrounded by a ring (4) having an index N+?n and thickness ?R, and cladding (6) surrounding the ring and comprising for example air gaps (8). According to the invention: ?n?10?3 and ?R=?/(?n)? [1] where: 5×10?4 ?m???5×10?2 ?m and 0.5???1.5. The numbers ? and ? are dependent on the wavelength ? of the light guided by the fiber, the number of missing gaps therein, the diameter d of the gaps, the spacing ? thereof and N. To design the fiber, ?, the number of missing gaps, d/?, the core doping content, ? and ?n are chosen; and ?R is determined using equation [1] so as to obtain a flattened fundamental mode.
