  • Low loss optical switching system
    Patent number: 7003188
    Abstract: An optical switching system that switches the path of an optical signal by moving a microstructure onto which a light-guiding structure is mounted. The microstructure is formed by a MEMs and semiconductor process to be integral to the substrate. The light-guiding structure may include waveguides. The microstructure moves from one position to another position (e.g., laterally, vertically, rotationally) such that incoming optical signals align over a small air gap to different optical paths, depending on the position of the movable microstructure. As a result, the optical signal propagate along different optical paths (e.g., straight pass through or cross over) depending on the position of the movable microstructure. The optical paths have a large radii of curvature so as to change the direction of the optical signal gradually, thereby reducing insertion losses.

  • Method of configuring a computer system capable of being woken up on LAN
    Patent number: 6993670
    Abstract: A method of configuring a computer system capable of being woken up on a LAN A core power is actuated for an interval by performing a Pre-Advanced Configuration and Power Interface (Pre-ACPI) routine. Next, a PCI clock signal is retrieved in the fixed interval and then an Ethernet ID is loaded using the PCI clock signal, so as to set a south bridge to a standby mode capable of receiving a wake-up event. As a result, use of an oscillator in conventional methods can be reduced, and the computer system can be configured to be capable of being woken-up on LAN, without requiring the start-up procedure, so that the computer system may be awoken on the LAN even after an abnormal shutdown.

  • 1×N or N×1 optical switch having a plurality of movable light guiding microstructures
    Patent number: 6990264
    Abstract: A 1×N or N×1 optical switch based on a plurality of movable MEMS-created platforms, each carrying a light guiding structure such as a waveguide, where the position of the platforms determines which optical path is connected through the optical switch.

The waveguides residing on the movable platforms gradually change the direction of the optical signal in order to minimize losses. The movable platforms can move linearly or rotationally, for example. Also described is a method for fabricating such an optical switch and its components by etching from the bottom of the substrate and through the oxide.
