We present a model for phase noise that fits experimentally observed trends in our high performance optomechanical oscillators (OMO) demonstrating a phase noise of -102dBc/Hz at 1kHz offset from a 74MHz carrier. ...
We present a fully integrated detector suitable for active tracking of interventional devices in MR-guided interventions. The single-chip microsystem consists of a detection coil, a tuning capacitor, an intermediate frequency downconversion receiver, and a ...
A quantum particle can be localized in a disordered potential, the effect known as Anderson localization. In such a system, correlations of wave functions at very close energies may be described, due to Mott, in terms of a hybridization of localized states ...
In small to medium size rooms, natural room modes may severely strengthen the annoyance of low frequency noises, such as traffic or equipment noise. Moreover, there is an actual technological gap in the state-of-the-art concerning low-frequency treatments, ...
A self-sustained Radiation-Pressure driven MEMS ring OptoMechanical Oscillator (RP-OMO) attaining an anchor-loss-limited mechanical Q-factor of 10,400 in vacuum has posted a best-to-date phase noise of -102 dBc/Hz at a 1 kHz offset from a 74 MHz carrier, m ...
We have developed an in situ method to calibrate optical tweezers experiments and simultaneously measure the size of the trapped particle or the viscosity of the surrounding fluid. The positional fluctuations of the trapped particle are recorded with a hig ...
We report on measurements of phase noise dynamics of microwave beat notes observed in low repetition rate silicon nitride based Kerr-comb generators and relate them to results from dispersion simulations and measurements. (C) 2011 Optical Society of Americ ...
We experimentally investigate the initial dynamics of Kerr-frequency comb formation in crystalline MgF2 and planar Si3N4 microresonator and present a universal, platform independent condition for low phase noise performance. ...
Phase-noise mechanisms in cross-coupled LC voltage-controlled oscillators (VCOs) are reviewed based on a physical understanding of reactive power imbalances in the tank and in the active part. These phenomena are proven to be the predominant phase-noise de ...
