  • Publication number: 20060263007
    Abstract: The present invention provides a fiber Bragg Grating sequential writing method with real-time optical fiber position monitoring, characterized in that the relative phase between a fiber grating and a writing interference beam at each positioning point is determined by an interferometric side-diffraction method, and writing is sequentially performed. Accuracy in fabricating a long and complex fiber grating structure can be increased by decreasing or avoiding accumulative errors caused by long-term scan of monitoring optical fiber position, or by a means for fabricating a wanted reference fiber Bragg grating with similar settings.

  • Publication number: 20060256685
    Abstract: The present invention relates to a system for recording a datum onto a pixel on a light-sensitive sheet. The main component of the system is a recording unit, which further includes a light-emitting device and at least one light-guiding device. Once the light-emitting device emits a light, the light enters the light-guiding device from an entrance and is transmitted out from an exit. Before the datum is recorded, the recording unit is moved so as to align the exit of the light-guiding device with the pixel. Thereby, the light transmitted out from the exit of the light-guiding device is further projected onto the pixel to record the datum on the pixel.

  • Publication number: 20060084288
    Abstract: An LGA connector is used to interconnect an LGA package and a printed circuit board. The LGA connector includes an elastomeric body with a plurality of through-holes. Metal films are formed on inner walls of through-holes and splay out around the mouths of their upper and lower openings. The metal films are formed by vacuum metallization, sputtering, chemical plating, electrical plating or PVD. The through-holes have a funnel-like shape to absorb external stresses and redirect the stress to shrink the through-hole diameters. Moreover, the metal films' elastic deformation is larger than conventional metal conductive fillers so as to improve reliability.

  • Publication number: 20050260402
    Abstract: An organic layer, such as a porous low-K dielectric in an IC, contains pores open at its surface. To close the pores, the organic layer is contacted by a supercritical fluid that is a solvent for the layer. After a small amount of the surface and the wall of the open pores is solvated, a phase transition of the solvated organic material is effected at the surface to cover it with a dense, smooth, non-porous film that seals the open pores.

  • Patent number: 6963432
    Abstract: The present invention provides a two-beam interference exposure system that can be simply adjusted by rotating only one mirror. By placing a half-wave plate in one of the interference arms and precisely scanning the relative fiber position, the present invention can expose true apodized fiber Bragg gratings in a single scan by simultaneously rotating the angle of the half-wave plate. By rotationally switching the fast and slow axes of the half-wave plate, the present invention can also expose n-phase-shifted fiber grating by the same system.
