John W Stocker has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7141080
    Abstract: The invention describes a method and apparatus for deploying micromachined actuators in a plane which is orthogonal to the original fabrication plane of the devices. Using batch-processing, photolithographic procedures known in the micromachined electro-mechanical system (MEMS) art, a plurality of devices is constructed on a suitable substrate. The devices are then separated one from another by sawing and dicing the original fabrication wafer. The devices are rotated into an orthogonal orientation and affixed to a second wafer. The second wafer also contains circuitry for addressing and manipulating each of the devices independently of the others. With this method and apparatus, arrays of actuators are constructed whose plane of actuation is perpendicular to the plane of the array. This invention is useful for constructing N×M fiber optic switches, which direct light from N input fibers into M output fibers.

  • Patent number: 6801681
    Abstract: An optical switch is fabricated using micro-electro-mechanical system (“MEMS”) techniques. A thin mirror is fabricated in the major plane of the substrate and rotates about an axis perpendicular to the major plane to move into and out of an optical beam path. The mirror surface is open for chemical polishing and deposition, resulting in a high-quality mirror. In one embodiment, the backside of the mirror is patterned with reinforcing ribs. In another embodiment, a two-sided mirror is fabricated.

  • Patent number: 6785038
    Abstract: An optical cross-connect is fabricated on a substrate using individual MEMs dice with mirrors that rotate into and out of an optical beam path. Each die can be aligned to a single (input-output) pair of collimators in a fiber-optic switching system. An individually accessible magnetic drive on each die provides low power consumption when re-configuring the array in addition to fast switching speeds. The state of each die can be electronically sensed to verify proper array configuration and operation of each die.
