    摘要： The silicon fluid ejector of the present invention includes an electrostatically actuated micromachined positive displacement mechanism consisting of a piston, piston containment structure, piston retraction mechanism and an ejection orifice. These features provide for very low cost of production, high reliability and “on demand” drop size modulation. The fluid ejector mechanism can be easily produced via monolithic batch fabrication based on the common production technique of surface micromachining.

    摘要： An improved waveguide shuttle optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a waveguide shuttle platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alternative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

    摘要： A vent connects a chamber to the external atmosphere surrounding a device to equalize pressure within the chamber. The vent has a size and shape to allow pressure equalization to occur outside a normal operating cycle of the chamber and controls the pressure to prevent undesirable deflection of a membrane within the chamber and ensure proper operation of the device.

    摘要： An optical micro-electro-mechanical system (MEMS) switch is disclosed. In a preferred embodiment the optical MEMS switch is used as an M×N optical signal switching system. The optical MEMS switch comprises a plurality of optical waveguides formed on a shuttle for switching optical states wherein the state of the optical switch is changed by a system of drive and latch actuators. The optical MEMS switch utilizes a latching mechanism in association with a thermal drive actuator for aligning the waveguide shuttle. In use the optical MEMS switch may be integrated with other optical components to form planar light circuits (PLCs). When switches and PLCs are integrated together on a silicon chip, compact higher functionality devices, such as Reconfigurable Optical Add-Drop Multiplexers (ROADMs), may be fabricated.

    摘要： An optical switch for routing signals includes a latch receiver connected to a waveguide that routes the signals and an actuator that includes an upper plate, a lower plate and a latch connected to the lower plate, the lower plate of the actuator moving vertically when power is applied to the lower plate, causing the latch to move vertically and engage the latch receiver. A latching system includes a switch that includes a latch formed to include an extension on one end of the latch, the latch being driven by power, a latch receiver that is formed to receive the latch and a controller that controls the extension of the latch to engage the latch receiver when the power is applied to the latch, and controls the extension of the latch to lock in place against the latch receiver when the power is removed from the latch.
