Methods for fabricating silicon MEMS gyroscopes with upper and lower sense plates

MEMS-actuated optical switches can be implemented on photonic chips. These switches are compact, essentially planar, simple to implement and include only one moving MEMS component per switch. The switches exhibit low optical loss, require low power to operate, and are simple to control and easy to integrate with other optical devices. Each switch has two optical waveguides that are optically coupled in an ON switch state and not coupled in an OFF switch state. An end or a medial section of one of the two waveguides may translate between the ON and OFF states to affect the coupling. Alternatively, a coupling frustrator may translate between the ON and OFF states to affect the coupling.

An ultra-low noise sensor for magnetic fields comprises a mechanically resonant structure having a magnetized proof mass. The displacement of the proof mass due to a magnetic field provides a high resolution and highly amplified measurement of magnetic field fluctuations near the resonance frequency. A flux modulator may be used with the resonant structure to amplify magnetic fluctuations in a non-resonant frequency band. The resonant structure, combined with a high resolution readout device and a frequency-compensating numerical processor, can amplify magnetic fluctuations in a broad range of frequencies. A solenoid coil surrounding the resonant structure may be used to null the quasi-static earth's magnetic field and thereby increase the dynamic range of the sensor. Cryogenically cooling the resonant structure can improve the resolution of the sensor. A magnetometer that embodies features of the present invention is miniaturized and has improved amplification and resolution at room temperature.
