MEMS mirrors are capable of scanning at frequencies greater than 34 kHz. Both diffraction and dynamic deformation are dependent on the mirror size; increasing the mirror length decreases diffraction, but increases dynamic deformation. This paper presents an analytical formulation of mirror dynamic deformation for sinusoidally scanning rectangular mirrors, and measured data that corroborates the derived model. With this equation for dynamic deformation, we determine the optimal mirror size for a given scanning frequency, and the maximum achievable frequency of operation for a desired optical resolution.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

There are numerous advantages to fabricating chips out of polymeric materials, and as a result we have been able to rapidly and inexpensively fabricate active devices with moving parts, such as pinch valves and peristaltic pumps. We have also developed a microfabricated flow cytometry chip as a replacement for analytical pulsed field gel electrophoresis. Assays with these chips are two orders of magnitude faster than pulsed field gels and use a million times less material. Because they are detecting single molecules, their sensitivity is comparable to PCR based techniques. We have also developed a microfabricated fluorescence activated cell sorter and demonstrated its use in screening bacterial cells. The novel valve and pump components for on-chip fluidic manipulation that we developed in the course of this research will be useful for fabricating more complex chip designs for a variety of biotechnological applications.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

The optical microswitch consists of the waveguides and the micromirror actuators, all fabricated by the silicon layer on an SOI wafer. In the normally off-state, the micromirrors bypass the input signal to the output port. In the on-state, however, the actuated micromirrors provide optical interconnections between I/O ports and PD/LD, respectively. The present waveguide switch uses actuated micromirrors, thus providing more reliable optical path change than the conventional electro-optic or thermo-optic waveguide switches. In addition, we simplify the structure and the process of the microswitch by using the silicon waveguides and the silicon mirror-actuators, all fabricated by the ICP etching of an identical SOI wafer.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

Emphasis is put on the development of a Fourier transform spectrometer based on a Michelson interferometer. A new design of the existing chip has been realized in order to integrate an input fiber, a collimating system as well as a beam splitting plate. This new design allows to carry out spectroscopy with white light. In fact, since white light has a smaller length of coherence, the phase difference zero is extremely important to be well set, i.e. the optical path in each branch of the interferometer has to be equal. Finally, we present two other designs of spectrometers: a lamellar grating spectrometer and a Hadamard transform spectrometer.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.

Arrays of small thin micromachined structures with high thermal masses, are suspended above the underlying silicon substrate by supports that are extremely well thermally isolated from the substrate with a high thermal conductance. This high thermal isolation allows for efficient heating of the microstructure with small currents (the case for microemitters), or small amounts of infrared (IR) incident flux (for microbolometers). The low mass ensures that despite the low conductance, the thermal time constants are in the millisecond range. We show the basic microstructure design common to both microbolometers and microemitters.","PeriodicalId":148819,"journal":{"name":"2000 IEEE/LEOS International Conference on Optical MEMS (Cat.
