摘要： A number of methods and systems for overcoming stiction are provided. The systems include electro-mechanical systems capable of exerting a variety of forces upon areas prone to stiction. The systems can be MEMS arrays or other types of devices where stiction related forces occur. The methods include a variety of ways of causing movement in areas prone to stiction forces. Such movement can be vibrational in nature and is sufficient to overcome stiction, allowing a trapped element to be moveed to a desired location.

摘要： A wavelength router that selectively directs spectral bands between an input port and a set of output ports. The router includes a free-space optical train disposed between the input ports and said output ports, and a routing mechanism. The free-space optical train can include air-spaced elements or can be of generally monolithic construction. The optical train includes a dispersive element such as a diffraction grating, and is configured so that the light from the input port encounters the dispersive element twice before reaching any of the output ports. The routing mechanism includes one or more routing elements and cooperates with the other elements in the optical train to provide optical paths that couple desired subsets of the spectral bands to desired output ports. The routing elements are disposed to intercept the different spectral bands after they have been spatially separated by their first encounter with the dispersive element.

摘要： A modular optical router/switch construction system and method are described. In one aspect of the present invention, the modules provided are basic 1×N optical components and/or pass-through 1×N optical components, both of which have input/output (I/O) ports which are capable of detachably interconnecting. Pass-through 1×N optical components are like the basic 1×N optical components but include extra ports so that input light may “pass through” the component. In another aspect of the present invention, a bi-directional optical component capable of modular construction is provided. The bi-directional optical component has the same I/O ports as the basic 1×N optical component, but the bi-directional I/O ports are built to engage a duplex optical link (i.e., a link comprised of two optical fibers with signals going in two opposite directions).

摘要： A method and apparatus for monitoring MEMS-based optical switches and cross-connects. A plurality of partial reflectors are introduced into optical paths of the switch for reflecting light transmitted along the optical paths through a transparent substrate of the switch, without disturbing transmission of the light along the optical paths. The reflected light is transmitted through the substrate, which is preferably made of silicon and transparent to wavelengths of light used in DWDM systems. A photodetector array bonded to the underside of the substrate detects the light reflected by the plurality of partial reflectors through the substrate. The light detected by the photodetector array indicates the switching states and functionality of the switch, and can be processed by circuitry associated with the array.

摘要： A highly reliable optical communications equipment is offered, which can control light more accurately than heretofore (i.e., less restrictions are imposed on the amount of attenuation and on the resolution) and which is equipped with a latching function. The optical communications equipment includes a piezoelectric actuator, a moving body moved by the piezoelectric actuator as a drive source, a multi-coating filter for controlling light that is a signal medium by movement of the moving body, a drive circuit for controlling the position of the multi-coating filter via the actuator, and a control circuit. The piezoelectric actuator uses bending vibrations produced in a piezoelectric vibrating body as a power source. If the moving body is not moved for a given time, the control circuit sends a function keeping signal to drive the actuator to such an extent that the moving body does not move. Thus, the function of the actuator is maintained.

摘要： An optical switch includes a reflective element that may be moved into and out of the path of an input light beam without rotation about a hinge. The switch includes a right angle prism whose hypotenuse is an angularly-fixed reflective surface. The prism is fixed to a base platform that is pivotal about an underlying pivot member. A switchable electromechanical relay is energizable for selectively rotating the platform about the pivot member to move the prism in and out of the path of the input beam. A collimator fixed to the output face of the prism assures proper registration of the output with a beam when reflected.

摘要： An apparatus for selectively coupling fiber optic lines comprises an optical input selection device, an optical output selection device, and a rotatable coupling mechanism interconnecting the optical input selection device and the optical output selection device. The optical input selection device is rotatable about a first central axis, and comprises a first input end and a first output end. The first input end is disposed collinearly with the first central axis, and the first output end is disposed at a radially offset distance from the first central axis. The optical output selection device is rotatable about a second central axis, and comprises a second input end and a second output end. The second input end is disposed at a radially offset distance from the second central axis, and the second output end is disposed collinearly with the second central axis. Rotation of the coupling mechanism causes rotation of the first output end and the second input end.
