    摘要： A structure and method for an optical switch is provided that includes providing sidewall electrodes with steerable micro-mirrors to position and control micro-mirror movement. The structure and method includes using the sidewall electrodes in conjunction with electrodes underlying a micro-mirror to sense capacitance present between a micro-mirror and underlying electrodes and/or sidewall electrodes, and driving the electrodes underlying the micro-mirror and the sidewall electrodes to move the micro-mirror into an angular position. The electrode structures and methods of driving them may be used in systems with closed loop feedback control to reduce transient mirror settling time and provide substantial immunity to system perturbations when micro-mirrors switch an optical signal from an input fiber to an output fiber of the optical switch, or when a micro-mirror is held at an angular position over long time scales.

    摘要： In a recording transducer, radiant energy is incident to be coupled to a recording head via a path defined in the support (e.g., slider) for the head. The radiant energy may be directed via a fiber or lens (e.g., MEMS lens) through a channel defined in the slider. The slider may be keyed to accept the fiber or lens. The process for fabricating the channel in the slider the channel may include wafer level processing to form holes in the slider, to accept the fiber or lens. Wafer level MEM optical processing may be deployed to form integrated MEMS lens structures for an array of sliders.

    摘要： An apparatus includes a movable member, and first and second actuators coupled to the movable member at positions offset from a first axis that passes through a centroid of the movable member. A controller independently controls the first and second actuators to exert a first force on the movable member in a direction generally parallel to the first axis, thereby controlling both linear and rotational orientation of the movable member. The apparatus can further include third and fourth actuators coupled to the movable member at positions offset from a second axis that passes through the centroid of the movable member, and the controller can independently controlling third and fourth actuators.
