  • Shaped electrodes for micro-electro-mechanical-system (MEMS) devices to improve actuator performance and methods for fabricating the same
    Patent number: 6825967
    Abstract: Shaped electrodes for micro-electro-mechanical-system (MEMS) devices to improve actuator performance and methods for fabricating the same are disclosed. The shaped electrodes utilize its three-dimensional geometry to shape an electric field for electrostatic actuation for MEMS devices. For example, the height, width, length, sidewall slope, and layout of the shaped electrodes can be used to provide an optimum electric field in moving a MEMS mirror device. The shaped electrodes can provide electrostatic actuation at a low operating voltage and provide an optimum electric field for maximum tilt or angular range of motion for a MEMS mirror device. The shaped electrodes can be fabricated simply by using a pillar wafer and an electrode wafer. The pillar wafer can be used to form pillars as electrodes, or, alternatively, as barriers. A single substrate can also be used to form pillars and electrodes.

  • Optical switch having switch mirror arrays controlled by scanning beams
    Patent number: 6643425
    Abstract: An optical switch having switch mirror arrays controlled by scanning beams that reduce the amount of electrical connections required and reduce the complexity for constructing large optical switches. Movement of the switch mirror arrays is controlled by one or more scanning beams. The optical switch includes one or more arrays of optical switch inputs and outputs and one or more arrays of movable mirrors to direct light beams from the optical switch inputs to the optical switch outputs. The optical switch also includes one or more control elements to control the movable mirrors based on scanning beams directed to the one or more control elements.
