20090107630 | MECHANICALLY DECOUPLED OPTO-MECHANICAL CONNECTOR FOR FLEXIBLE OPTICAL WAVEGUIDES EMBEDDED AND/OR ATTACHED TO A PRINTED CIRCUIT BOARD - Printed circuit boards that include optical interconnects include a flexible optical waveguide embedded or locally attached to the board having at least one end mechanically decoupled from the board during fabrication that can be fitted with a mechanical connector. Also disclosed are processes for fabricating the circuit board. | 04-30-2009 |
20090110345 | METHODS FOR PASSIVE MICROMETER-RANGE ALIGNMENT OF COMPONENTS USING REMOVABLE REFERENCE STRUCTURES - A method for passive alignment of adapters, enabling high-precision connection between components on a rigid or flexible substrate as part of a printed circuit board (PCB) is provided. Removable alignment structures are positioned in an alignment area on a PCB, where the alignment structures are in accordance with a patterned layer. Alignment pins of a two-part connector are inserted into the holes of the alignment structures such that the two-part connector is aligned with the alignment structures on the substrate, and the two-part connector is a component that comprises an integrated adapter part and ferrule part. The ferrule part of the two-part connector is fixed on the substrate in the alignment area. The adapter part of the two-part connector is removed from the ferrule part of the two-part connector such that the ferrule part remains on the substrate. The alignment structures are removed from the substrate. | 04-30-2009 |
20090284684 | Coupling Device for Use in Optical Waveguides - An optical coupling device for coupling light with an optical waveguide comprises a mirror formed within an optical waveguide. The mirror comprises a first material, a first reflective end, and a second reflective end. The first material is light conducting and has a first refractive index. The first and second reflective ends reflect and transmit light. The mirror has an axis line. The optical coupling device is useful for extracting light from a waveguide and providing a backlight for a liquid crystal display. | 11-19-2009 |
20100046883 | Coupling Device for Use in Optical Waveguides - An optical waveguide device comprises a plurality of mirrors, wherein at least one mirror comprises a first and second reflective end that reflect and transmit light. The plurality of mirrors comprises at least one first material having at least one first refractive index; an axis line; a first cladding comprising a second material having a second refractive index; a second cladding, formed above the first, comprising a third material having a third refractive index; a core comprising a fourth material; and a plurality of core parts formed within at least one of the first or second claddings. The fourth material has a fourth refractive index that is greater than the second and third refractive indices and the core parts have a plurality of core part ends coupled to one of the reflective ends where at least one core part end is approximately parallel to one of the reflective ends. | 02-25-2010 |
20100067852 | METHOD FOR ASSEMBLING A FURRULE FOR AN OPTICAL WAVE GUIDE CONNECTOR, FERRULE, WAVE GUIDE RIBBON AND TOOL FOR ASSEMBLING THE FERRULE - A method for assembling a ferrule for an optical wave guide connector, a ferrule for an optical wave guide connector, a wave guide ribbon and a tool for assembling the ferrule. The method includes aligning a first body of the ferrule with respect to an alignment body. The first body includes a longitudinal recess adapted to receive at least one wave guide ribbon. Each wave guide ribbon includes at least one optical wave guide. The method further includes aligning at least one wave guide ribbon with respect to the alignment body and inserting the at least one wave guide ribbon into the longitudinal recess of the first body. Lastly, the method further includes closing the longitudinal recess of the first body with a second body of the ferrule. | 03-18-2010 |
20110317969 | Method and Spacer for Assembling Flexible Optical Waveguide Ribbons, and Assembled Stack of Such Ribbons - A method and spacer for assembling flexible optical waveguide ribbons and assembled stack of such ribbons. The method includes the steps of: providing at least two optical waveguide ribbons and a spacer, which includes at least two calibrated spaces; positioning a ribbon stack in the spacer, where the ribbon stack includes the at least two optical waveguide ribbons stacked on top of each other; constraining positioned ribbon stack in one of the calibrated spaces; and fixing constrained ribbon stack in the calibrated spaces. | 12-29-2011 |
20120039576 | OPTICAL WAVEGUIDE WITH EMBEDDED LIGHT-REFLECTING FEATURE AND METHOD FOR FABRICATING THE SAME - A method for fabricating an optical waveguide includes setting, on a lower cladding of an optical waveguide, a light-reflecting feature and at least one waveguide core distinct from the reflecting feature. An upper cladding is applied that embeds both the light-reflecting feature and the waveguide core. | 02-16-2012 |
