| 20100086256 | LIGHT COUPLER BETWEEN AN OPTICAL FIBRE AND A WAVEGUIDE MADE ON AN SOI SUBSTRATE - A light coupler between an optical fiber ( | 04-08-2010 |
| 20100098379 | STRUCTURE AND METHOD FOR ALIGNING AN OPTICAL FIBER ON AN OPTICAL WAVEGUIDE - An optical device including at least one first optical waveguide coupled to a second optical waveguide of smaller cross-section which penetrates into it on the side of a first end. The first optical waveguide is capable of being coupled with an optical fiber on the side of a second end. A surface of the first optical waveguide includes a diffraction grating capable of introducing-extracting-sending back light into and from the first optical waveguide. | 04-22-2010 |
| 20100172615 | Coupling Device with Compensated Birefringence - The invention relates to a coupling device comprising a support substrate; a first layer arranged on the support substrate and comprising first patterns produced within the thickness of said first layer, said first patterns being arranged in parallel and periodic rows; a second layer arranged on the first layer and comprising second patterns passing through the thickness of said second layer, said second patterns being arranged in parallel and periodic rows. The direction of periodicity of the rows of the first patterns is perpendicular to the direction of periodicity of the rows of the second patterns. The rows of the first patterns extend over a distance greater than or equal to the wavelength in the void of the optical wave intended to be coupled. The first patterns have a width less than or equal to a tenth of the wavelength of the optical wave intended to be coupled, and the period of these patterns is between 50 nm and 1 μm. The second patterns are arranged so as to form a periodic diffraction grating. | 07-08-2010 |
