  • Patent number: 6856749
    Abstract: An optical device, such as optical coupling devices, optical switches, optical isolators, optical attenuators, laser diodes, photo diodes are provided having a substrate with a groove in order to locate a optical fiber. A lens, such as a graded index lens, is secured to the end of the optical fiber, with the lens located outside the groove, thereby avoiding difficulties with axial alignment of the lens caused by the interface of the optical fiber to the lens. In one implementation, the groove in the prototype is a V-groove, thereby providing stable positioning of the optical fiber within the groove.

  • Publication number: 20030156451
    Abstract: Microelectromechanical (MEMS) devices that use MEMS electromagnetic actuators to selectively generate displacement forces are disclosed herein. According to one exemplary embodiment disclosed herein, a MEMS device may include a substrate having a surface, an actuable element at least partially formed from the substrate, and an electromagnetic actuator disposed on the substrate for selectively applying a first force to the actuable element to displace the actuable element along a path. The actuable element may have a base and an arm coupled to the base. The base may include a portion comprised of a magnetic material. The electromagnetic actuator may comprise an electrically conductive coil, and the path of the actuable element may pass through a coil gap in the coil. The electromagnetic actuator may also comprise a magnetic core about which the electrically conductive coil may be wound.
