    摘要: The device comprises a parallel input microguide (2) and output microguide (5) between which a flat guide is arranged forming a transition zone (10). Coupling between the flat guide and the microguides is achieved by an optical tunnel effect. The transition zone comprises at least two zones, a reference zone (10a) and an interaction zone (10b). The interaction zone (10b) is formed by depositing a superstrate whose optical coefficient, or thickness, is sensitive to the medium to be studied. The light beam transmitted by the input microguide to the flat guide is divided into a reference beam passing through the reference zone (10a) and a measurement beam passing through the interaction zone (10b). The measurement and reference beams interfere in the output microguide (5). Depending on the geometrical shape of the reference and interaction zones, the device constitutes a double wave or a multiple wave interferometer. Such a device is used to achieve sensors for applications in physics, chemistry and biology.

    摘要: The device uses the principle of the Doppler effect laser velocimeter. It comprises emitter and receiver optic guides formed by integrated optics techniques on a single substrate, preferably made of glass. The emitter guides, connected to a light source, produce two mutually coherent beams inclined with respect to one another in such a way as to constitute interference fringes in a measuring volume situated outside the substrate. The receiver guides transmit the light diffused by the passage of particles in movement through the measuring volume to a detection and processing circuit. The substrate is mounted in a support fixed in an orifice of a wall along which a fluid flows transporting the particles to be examined. The substrate comprises a face which comes into contact with the fluid. This device enables the velocity, size and/or number of particles in movement in a fluid moving along a wall to be determined.

    摘要: The integrated-optics coupling component is designed to cooperate with a transverse multimode power laser diode (2) with semi-conductor to form a transverse multimode power laser. It comprises an input zone (4) connected to at least one output waveguide (6) by at least two adiabatic tapering zones (5). At least two filtering windows (7) form the inputs of the adiabatic tapering zones (5) at the end of a diffraction zone defined by the input zone. Reflecting elements, for example a Bragg grating (12), can be arranged on the output waveguide. An emitting face (3) being antiglare-treated, an extended laser cavity oscillating on a single predetermined mode is thus defined between a reflecting rear face (11) of the laser diode and the reflecting elements (12).

    摘要: The component comprises structures, achieved in integrated optics, exerting predetermined stresses on a light wave guiding waveguide so as to maintain or modify in predetermined manner the polarization state of an incident light wave. These structures are formed by at least one segmented plane waveguide arranged laterally with respect to the light wave guiding waveguide and formed by parallel lateral waveguides perpendicular to the longitudinal axis of the light wave guiding waveguide. These structures are achieved at the same time as the light wave guiding waveguide, the segmented plane waveguides having refractive indexes lower than or equal to those of the light wave guiding waveguide. Such structures can be arranged symmetrically or asymmetrically, alternately on each side of the light wave guiding waveguide.
