General design rules and the scaling laws with wavelength for MEMS tunable optical filters are discussed for the first time. We describe how to determine dimensions and component materials from the system requirements such as tuning range, central wavelength, tuning voltage, tuning speed and resolution. The systematic design allows fair comparison among different topologies such as cantilever, ...

MEMS Accelerometer, the new inventions which revolutionized the technical world. Now, it’s time for the self assistive accelerometers. In this paper, we have designed the trampoline, annular diaphragm structured piezoelectric accelerometers using PZT-5H with COMSOL Multiphysics software tool for providing low transverse sensitivity along one axis and good temperature stability. These accelerome...

We have observed the interferometric suspension of a free-falling Bose-Einstein condensate periodically submitted to multiple-order diffraction by a vertical 1D standing wave. The various diffracted matter waves recombine coherently, resulting in high contrast interference in the number of atoms detected at constant height. For long suspension times, multiple-wave interference is revealed throu...
