A critical element for inertial navigation is precise knowledge of the angular kinematics which are measured using gyroscopes. Optomechanics has been shown to be the most sensitive scheme for measuring mechanical motion [1, 2]. In this paper, we demonstrate electrostatic actuation and optical sensing of orthogonal wineglass modes on a silicon-on-insulator (SOI) platform as a fundamental building block...
We show operation of a silicon MEMS based narrow-band optical modulator with large modulation depth by improving the electro-mechanical transducer. We demonstrate an application of the narrowband optical modulator as both the filter and optical modulator in an opto-electronic oscillator loop to obtain a 236.22 MHz Opto-Acoustic Oscillator (OAO) with phase noise of −68 dBc/Hz at 1 kHz offset.
