Abstract: A MEMS device having a fixed element and a movable element wherein one or the other of the fixed element and the movable element has at least one radially-extended stop or overdeflection limiter. A fixed overlayer plate forms an aperture. The aperture is sized to minimize vignetting and may be beveled on the margin. Overdeflection limitation occurs during deflection before the movable element can impinge on an underlying electrode. The overdeflection limiter may be conveniently placed adjacent a gimbaled hinge.

Abstract: In an electrostatically controlled apparatus, such as a MEMS array having cavities formed around electrodes and which is mounted directly on a dielectric substrate in which are embedded electrostatic actuation electrodes disposed in alignment with the individual MEMS elements, a mechanism is provided to controllably neutralize excess charge and establish a controlled potential between the MEMS elements and the electrostatic actuation electrodes.

Abstract: A method is provided for calibrating a free-space-coupled fiber-optic transmission system. The method uses signal content in the measured coupled power at frequencies equal to the sum, difference, and first harmonics of the frequencies of control-related dither signals to infer and correct errors in the kinematical model used to apply the dithers. The technique can operate independently or simultaneously with dither-based functions such as alignment control and power attenuation to provide continuous tracking of model terms. The calibration method does not require that any calibration-specific signals be injected into the system, or that the operation of primary functions be halted for the purpose of calibration.

Abstract: A method for generating optical paths in a photonic network is provided. A model of a photonic network is used to store relationship information that describes the relationships between photonic network elements, as well as configuration information about the elements of the photonic network. A path manager receives a request to generate one or more paths based on an input port and one or more output ports. Using the information stored in the photonic network model, the path manager generates one or more candidate paths.

Abstract: Methods and apparatus are provided for detection and control of multiple-axis active alignment for a free-space-coupled single-mode fiber-optic transmission system that automatically optimizes the coupling through the system. In a specific embodiment, a measurement of coupled power is made and error signals 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 four errors.

Abstract: A MEMS-based mirror is provided with trenches between adjacent electrodes in order to be able to withstand relatively high applied voltages, and thus has a substantially reduced exposure to uncontrolled surface potentials. The MEMS-based mirror, thus avoids voltage drifts and has an improved mirror position stability. The trench dimensions are selected such that the voltage applied between each adjacent pair of electrodes stays within predefined limits. An insulating layer, such as silicon dioxide, electrically isolates each pair of adjacent electrodes. Each insulting layer extends partially above an associated trench and is characterized by the same height and width dimensions.
