    摘要： The present invention provides an all optical cross connect switch utilizing two-axis MEMS mirrors for cross connecting optical fibers in a first set of optical fibers to optical fibers in a second set of optical fibers. The optical fibers in the first and second sets of optical fibers are precisely positioned in a first fiber-microlens positioning array to define a first set of parallel collimated cross-connect communication beam paths, with each collimated cross-connect communication beam path connecting an optical fiber in the first set of optical fibers with a MEMS mirror in a first MEMS mirror array. Alignment beams are added to and aligned co-axially with each of the first and second sets of parallel collimated cross-connect communication beams. Two beam direction sensor units are positioned to detect each alignment beam in the first and second sets of alignment beams transmitted through the dichroic mirror and a MEMS control system controls the positions of the MEMS mirrors to connect optical fibers in the first set of optical fibers to any of the optical fibers in the second set of optical fibers.

    摘要： A scalable optical switch especially useful for switching multimode beams carried by optical fibers. Light from an input fiber is focused by a lens which is moved in an x-y direction perpendicular to the beam direction in order to switch the beam from one output fiber to a different fiber. In preferred embodiments the beam can be directed to any one of as many as 90 output fibers. Techniques for scaling the switch to produce N×N switches with N being large are described. Embodiments of the present invention can also be utilized to create more elaborate fiber optical switches such as an N×N switch and a N2×N switch.

    摘要： A low cost, multimode optical fiber switch in which a MEMS mirror is used to serially reflect input light from a plurality of input optical fibers into a single output fiber or from a single optical fiber into a plurality of output fibers. In a planned demonstration prototype the output fiber is located in the center of four input fibers. In other preferred embodiments of the present invention an array of MEMS mirrors are utilized with a large bundle of fibers containing both input and output fibers. Each MEMS mirror is adapted to reflect light from a number of input fibers one-at-a-time into a single output fiber or to reflect light from a single input fiber into a number of output fibers one-at-a-time.

Tortional elements with conductive comb fingers are utilized to provide the two axis actuation. A MEMS mirror control system supplies electrical voltage potentials between inside pivoting support frame conductive comb fingers and mirror frame conductive comb fingers and supplies electrical voltage potentials between MEMS mirror array support frame conductive comb fingers and outside pivoting support frame conductive comb fingers.
