    Abstract: In a gimbaled micromachined micromirror array optimized for parallel-plate electrostatic operation, longitudinal-type gimbal hinge elements are provided in which a plurality of torsional longitudinal hinge elements are arranged in an array parallel to the axis of rotation and which are linked together by rigid lateral brace sections. In primary embodiment the hinge elements are arranged in a double gimbal configuration. Specific embodiments of the hinge elements are simple longitudinal, compound longitudinal, stacked simple longitudinal, and stacked compound longitudinal. The longitudinal hinges may be used with various types of mirrors including circular or rectilinear, recessed or nonrecessed, where the hinges are connected in either a symmetric or asymmetric configuration relative to one another, as hereinafter illustrated by way of a subset of examples. A preferred embodiment of a mirror structure suitable for an array structure according to the invention is a nonstacked compound longitudinal hinge symmetrically connected to a circular nonrecessed electrostatically-actuatable parallel plate mirror within a substantially circular ring hinged in substantially the same way to form a double gimbaled structure.

    Abstract: Methods and apparatus are provided for detection and control of multiple-axi s active alignment for a free-space-coupled single-mode fiber-optic transmissi on system that automatically optimizes the coupling through the system. In a specific embodiment, a measurement of coupled power is made and error signal s are used to control actuation via four axes of beam steering element to null four generally orthogonal alignment errors of the beam between the input (12 ) and output fibers (14). The four alignment errors are detected using a synchronous-detection approach. A feedback control system (100) nulls the fo ur errors.

    Abstract: In an electrostatically controlled deflection apparatus, such as a MEMS array having cavities formed around electrodes and which is mounted directly on a dielectric or controllably resistive substrate in which are embedded electrostatic actuation electrodes disposed in alignment with the individual MEMS elements, a mechanism is provided to mitigate the effects of uncontrolled dielectric surface potentials between the MEMS elements and the electrostatic actuation electrodes, the mechanism being raised electrodes relative to the dielectric or controllably resistive surface of the substrate. The aspect ratio of the gaps between elements (element height to element separation ratio) is at least 0.1 and preferably at least 0.5 and preferably between 0.75 and 2.0 with a typical choice of about 1.0, assuming a surface fill factor of 50% or greater. Higher aspect ratios at these fill factors are believed not to provide more than marginal improvement.

    Abstract: Methods and apparatus are provided for the closed loop attenuation of optical beam power in a multiple-axis free-space-coupled single-mode fiber-optic transmission system. In a specific embodiment involving two tip-tilt mirrors to couple optical power from an input fiber to an output fiber, the four mirror axes are actuated in such a way as to produce either a static or time-varying set of induced mirror angles that yield a desired time history of optical loss. The attenuation technique uses the DC level of the measured output power to adjust the amplitude of the induced mirror angles.

    Abstract: Method for fabricating ultrathin gaps producing ultrashort standoffs in array structures includes sandwiching a patterned device layer between a silicon standoff layer and a silicon support layer, providing that the back surfaces of the respective silicon support layer and the standoff layer are polished to a desired thickness corresponding to the desired standoff height on one side and to at least a minimum height for mechanical strength on the opposing side, as well as to a desired smoothness. Standoffs and mechanical supports are then fabricated by etching to produce voids with the dielectric oxides on both sides of the device layer serving as suitable etch stops. Thereafter, the exposed portions of the oxide layers are removed to release the pattern, and a package layer is mated with the standoff voids to produce a finished device. The standoff layer can be fabricated to counteract curvature.
