    Abstract: A microelectromechanical system (MEMS) mirror assembly includes a base substrate defining a cavity and a plurality of first features extending upwards from a bottom of the cavity. The MEMS mirror assembly includes a mirror substrate coupled to the base substrate and defining a MEMS actuator and a MEMS mirror platform. Actuation of the MEMS actuator moves the MEMS mirror platform from a first positional state to a second positional state. The MEMS mirror platform defines a plurality of second features on a side of the MEMS mirror platform facing the base substrate that are sized, shaped, and positioned such that the plurality of second features extend into spaces separating the plurality of first features when the mirror platform is in the second positional state. The MEMS mirror assembly includes a reflective material disposed on a side of the MEMS mirror platform facing away from the base substrate.

    Abstract: A three-degrees-of-freedom MEMS electrostatic piston-tube actuator is disclosed. The actuator comprises two structures. A structure that comprises a plurality of fixed piston-like electrodes that are attached to a base, and form the stator of the actuator. A second structure that comprises a plurality of moving tube-like electrodes that are attached to the body of the upper structure and form the rotor of the actuator. The rotor is attached to the stator through a mechanical spring. The rotor of the actuator provides a 3-DOF motion, comprising vertical translation and bi-axial rotation about the axes of the structures. The present piston-tube actuator utilizes a configuration that enables the use of wide area electrodes, and therefore, provides a high output force enabling translation of the rotor or a high output torque enabling rotation of the rotor.

    Abstract: Wavelength division multiplexing (WDM) has enabled telecommunication service providers to fully exploit the transmission capacity of optical fibers. State of the art systems in long-haul networks now have aggregated capacities of terabits per second. Moreover, by providing multiple independent multi-gigabit channels, WDM technologies offer service providers with a straight forward way to build networks and expand networks to support multiple clients with different requirements. In order to reduce costs, enhance network flexibility, reduce spares, and provide re-configurability many service providers have migrated away from fixed wavelength transmitters, receivers, and transceivers, to wavelength tunable transmitters, receivers, and transceivers as well as wavelength dependent add-drop multiplexer, space switches etc. However, to meet the competing demands for improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, re-configurability, and lower cost it is desirable to exploit/adopt are monolithic optical circuit technologies, hybrid optoelectronic integration, and microelectromechanical systems (MEMS).
