High-quality frequency references are the cornerstones in position, navigation and timing applications of both scientific and commercial domains. Optomechanical oscillators, with direct coupling to continuous-wave light and non-material-limited f × Q product, are long regarded as a potential platform for frequency reference in radio-frequency-photonic(More)
We demonstrate a novel technique for reducing the phase modulation (PM) noise of an oscillator in a steady-state condition as well as under vibration. It utilizes correlation between PM noise and amplitude modulation (AM) noise that can originate from the oscillator's loop components. A control voltage proportional to the correlated AM noise is generated(More)
I. Chip layout and experiment setup The chip layout is shown in Figure S1. For compactness on the CMOS chip, we placed our integrated OMO as center symmetric pairs. Here the inverse oxide taper coupler is shown in red on both input/output coupling sides and the silicon waveguide is shown in blue. The Ge detector is shown in dark purple, with the electrodes,(More)
