Abstract: An optical micro-electro-mechanical system (MEMS) switch is disclosed. In a preferred embodiment the optical MEMS switch is used as an M .times. N optical signal switching system. The optical MEMS switch comprises a plurali ty of optical waveguides formed on a cantilever beam platform for switching optica l states wherein the state of the optical switch is changed by a system of drive and latch actuators. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning the cantilever beam platform. In use the optical MEMS device 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 A dd- Drop Multiplexers (ROADMs), may be fabricated.

Abstract: A microstructure that may be used as an electrical connection in a microfabricated electro-mechanical system (MEMS) apparatus. The microstructure may have one or more isolatable electrical connections for signal transmission. The microstructure allows a MEMS apparatus to shield signal transmissions from the effects of electromagnetic interference or conductive fluids.

Abstract: The present invention provides a micromechanical or microoptomechanical structure produced by a process comprising defining the structure in a single-crystal silicon layer separated by an insulator layer from a substrate layer; selectively etching the single crystal silicon layer; depositing and etching a polysilicon layer on the insulator layer, with remaining polysilicon forming mechanical elements of the structure; metalizing a backside of the structure; and releasing the formed structure.
