    摘要: Optical switch packaging techniques and optical switch components are described. In one aspect, an optical switch component that includes a die mounted on an interposer is described. The die has an exposed array of mirrors that can be used as part of an optical switch. Typically, the interposer will also have a fiber array mount arranged to receive a fiber bundle and to position the fiber bundle appropriately over the array of mirrors. In some embodiments, an optical switch can be formed by putting together two mirror image interposer based optical switch components. When placing two interposer based optical switch components together, an alignment frame may be positioned between the interposers to help maintain a desired spacing between the respective arrays of mirrors. In some such embodiments, an inner housing is provided that encloses the dice, the fiber array mounts the alignment frame and portions of the interposers, but leaves connectors mounted on the interposers exposed. An outer housing may optionally be provided to encase the optical switch components and the inner housing. A resilient filler material may also be provided between the inner and outer housings to provide additional protection to the optical switch.

    摘要: A micro-electro-mechanical-system (MEMS) mirror device and methods for fabricating the same allow for a large range of angular motion for a center mirror component. The large range of angular motion for a center mirror component is dictated simply by a thickness of a substrate used or a thickness of a thick film used in making a support structure to support the center mirror component. The MEMS mirror device and methods for fabricating the same allow a large number mirror devices to be fabricated on a substrate. The MEMS mirror device includes a substrate. Electrodes are formed supported by the substrate. A support structure is formed adjacent to the electrodes. A hinge pattern and a mirror pattern having a center mirror component are formed such that the support structure supports the hinge pattern and mirror pattern. The support structure also supports the hinge pattern and mirror pattern such that a bottom surface of the center mirror component in a stationary non-rotating position is capable of exceeding a height of 50 &mgr;m above the electrodes.

    摘要: A system is described for providing selectable delay. A first converter converts a first electromagnetic signal into an optical signal. An optical switch is coupled to the first converter to provide selectable delay by selection of paths by a plurality of movable microelectromechanical system (MEMS) mirrors. The paths have respective measurable differences in delay for the optical signal. A second converter coupled to the optical switch converts the optical signal into a second electromagnetic signal. The differences in delay for the optical signal result in differences to delay for the second electromagnetic signal in comparison to the first electromagnetic signal. Relatively short delays are provided by the optical switch and relatively long delays are provided by a plurality of fiberoptic delay lines.

    摘要: The disclosed embodiments include method and apparatus for detecting the alignment of movable reflectors in an optical switch. A diagnostic device embodiment includes a two-dimensional photoimager positioned to receive light from movable mirrors in the switch. Each movable mirror reflects light to different two-dimensional positions on the photoimager based on the position of each movable mirror, thereby creating a two-dimensional image of the reflector array. A controller receives information from the photoimager and adjusts the positions of the movable mirrors according to light received at the photoimager. A related diagnostic device includes an illumination source for directing monitor light beams onto the movable mirrors where the monitor beams are reflected onto the photoimager. This configuration provides two-dimensional information concerning the current position of the movable mirrors which is used to monitor and adjust the positions of the movable mirrors of the switch.

    摘要: An optical switch is described having mirrors that are located over an area having an approximate oval shape. Each mirror is pivotable about a first axis and about a second axis transverse to the first axis. Because of the construction and assembly of each mirror, pivoting about the first axis is more limited than pivoting about the second axis. The area over which the mirrors are located is designed to accommodate pivoting about the first axis and about the second axis such that the area has a length and a width wherein the length is much more than the width. In addition, pivoting about the first axis limits pivoting about the second axis and pivoting about the second axis limits pivoting about the first axis. Because pivoting about one axis limits pivoting about another axis, the area over which the mirrors are located has an oval shape as opposed to a rectangular shape.

    摘要: A method and apparatus are described to provide optical path protection for an optical switching system. An apparatus includes a first optical core switch, a second optical core switch, and an optical protection switch. The optical protection switch has at least two inputs and at least two outputs that allow the optical protection switch to direct input optical data traffic to one of the first optical core switch and the second optical core switch, and to direct a test signal to the other of the first optical core switch and the second optical core switch. For one embodiment, the optical protection switch is a 2×2 non-blocking optical switch having only two-path loss optimization. Alternatively, the optical protection switch may be a blocking 3×2 optical switch implemented to function as a 2×2 non-blocking optical switch. For one embodiment, the blocking 3×2 optical switch is a translational switch.
