Polysilicon films deposited by LPCVD exhibit tensile or compressive residual stresses, depending on the deposition temperature. Polysilicon films comprised of alternating tensile and compressive layers can display any overall value of stress and stress gradient. We call the multilayer material MultiPoly/sup TM/ and the process the MultiPoly/sup TM/ process. Structures made from these films can be designed to display deliberate curvatures as-fabricated resulting in novel optical devices, such as focusing mirrors. Electrostatic actuation can be used to modify the shapes of these polysilicon structures, creating optical switches.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

In an RSOD the traditional translating mirror is replaced by a scanning mirror with a rotation angle of a few degrees. We present the integration of a scanning silicon micromirror into a compact RSOD geometry only about 5 cm in length. We demonstrate a 40 ps rapid scanning optical delay of 100 fs time scale optical pulses. Our RSOD is based on a surface micromachined tilt-up mirror. The polysilicon mirror is connected to a supporting frame with torsional polysilicon beams and is dynamically driven by an electrostatic comb-drive actuator. The rectangular mirror face is 760 /spl mu/m by 500 /spl mu/m, with a resonant frequency of 1060 Hz and a measured range of deflection of 16 degrees optical. The residual stress gradients give the micromirror a measured convex radius of curvature of 34 cm. The RSOD is characterized using a Michelson interferometer. The frequency and deflection characteristics of the micromirror are presented.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

Solutions have been developed to overcome the technological hurdles encountered. The elementary 1/spl times/2 switch performances have been strongly improved: very low crosstalk (<-42 dB), low optical losses (1.5 dB), insensitivity to wavelength (<0.2 dB, 1250-1650 nm wavelength range) and polarisation (<0.3 dB), low driving voltage (<70 V), low switching time (<5 ms). Due to the results associated with a size reduction and a very accurate and reproducible control of residual deflection, we have demonstrated that the fabrication of larger 1/spl times/N switches is possible by cascading 1/spl times/2 switches. 1/spl times/8 switches have been fabricated. Moreover an 8/spl times/8 switching matrix has been demonstrated using arrays of 1/spl times/8 switches. These demonstrations show that this technology can address the different switching applications.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

This switch can be cascaded into 1/spl times/N structure. The layout and layer cross section of the waveguide are shown schematically. Actuation is accomplished by electrostatic means, by application of bias between the movable waveguide and static electrodes. This results in 4 /spl mu/m motion of the cantilevered waveguide in the plane of the wafer. The waveguide consists of 4 /spl mu/m thick GaAs/AlGaAs layer, while the release layer is composed of 2 /spl mu/m of Al/sub 0.7/Ga/sub 0.3/As. Metal contacts are deposited on a planar substrate prior to waveguide definition. Then 3 /spl mu/m wide waveguide is defined by RIBE. Photoresist is defined on the areas to be protected against release and sacrificial layer is removed by a HF-based wet etch. After photoresist removal, devices are sublimation dried. Fabrication issues, such as choice of materials, release chemistries and their implications are further discussed. Also, further details of device performance are given.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

The probes are fabricated of a transparent photoplastic material (SU-8) which allows simple batch fabrication based on spin coating and subsequent near-ultraviolet exposure and development steps. SU-8 consists of the epoxy-based EPON SU-8 resin photosensitized with a triaryl sulfonium salt. The main interest for MOEMS applications is that SU-8 is transparent. These combined advantages are used here to define a sharp, transparent and high aspect ratio probe dedicated for near-field optical applications.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.
