  • Low loss directional coupling between highly dissimilar optical waveguides for high refractive index integrated photonic circuits
    Patent number: 8787712
    Abstract: An optocoupler, an optical interconnect and method of manufacture providing same are provided for coupling an optical signal between a high refractive index waveguide of an integrated circuit and a waveguide external to the integrated circuit. The optocoupler includes a thinned high refractive index waveguide having a thickness configured to exhibit an effective refractive index substantially matching a refractive index of the external waveguide.
    Type: Grant
    Filed: December 29, 2011
    Date of Patent: July 22, 2014
    Assignee: Socpra Sciences et Genie S.E.C.
    Inventors: Etienne Grondin, Guillaume Beaudin, Vincent Aimez, Richard Ares, Paul G. Charette

  • Integrated shear-vertical surface acoustic wave and surface plasmon resonance sensing device and method
    Patent number: 8508742
    Abstract: A device and method detect a feature of a fluid or a target element in the fluid by contacting the fluid to a sensing surface on a substrate. A mechanical wave comprising shear-vertical wave components is propagated through the substrate to mix the fluid, conduct desorption of at least one non-target element from the sensing surface, and/or impede adsorption of the non-target element to the sensing surface. The feature of the fluid or the target element in the fluid is then detected on the sensing surface, wherein the detection is accelerated by the above-mentioned mixing of the fluid, desorption of at least one non-target element from the sensing surface, and/or impeding of the adsorption of the non-target element to the sensing surface.

  • Apparatus and method for rapid 3D image parametrization
    Patent number: 6101269
    Abstract: A method and apparatus for rapid three dimensional geometry parametrization of a three dimensional surface. A random speckle pattern is projected upon the surface and imaged to obtain a plurality of two dimensional digital images. The two dimensional images are processed to obtain a three dimensional characterization of the surface. The illuminated surface may be modeled to obtain a parameter set characterizing the surface based upon the two dimensional digital images.
