  • Base, payload and connecting structure and methods of making the same
    Patent number: 7113688
    Abstract: Micromachined passive alignment assemblies and methods of using and making the same are provided. The alignment assemblies are used to align at least one optical element. The alignment assemblies may be configured with kinematic, pseudo-kinematic, redundant or degenerate support structures. One alignment assembly comprises a base and a payload, which supports at least one optical element. The payload may be coupled to the base via connecting structures. The base, the payload and/or the connecting structures may have internal flexure assemblies for preloading a connection, thermal compensation and/or strain isolation.
    Type: Grant
    Filed: January 18, 2005
    Date of Patent: September 26, 2006
    Assignee: Siimpel Corporation
    Inventors: Robert J. Calvet, Roman C. Gutierrez, Tony Kai Tang

  • High density fiber terminator/connector
    Patent number: 6595698
    Abstract: A high density fiber terminator/connector and methods of making the high density fiber terminator/connector are provided. One method comprises using deep reactive ion etching to etch a plurality of holes through a silicon substrate, wherein each hole is sized to fit an optical fiber; placing an optical fiber in at least one hole; removing portions of the fibers such that one end of each fiber is substantially even with one side of the substrate; polishing a surface of the ends of the fibers and the side of the substrate that are substantially even; and forming a coating on the surface of the ends of the fibers and the side of the substrate that are substantially even.
