Phase-Locked, Low-Noise, Frequency Agile Titanium: Sapphire Lasers for Simultaneous Atom Interferometers [PDF]

open access: yes, 2005
We demonstrate phase lock of two >1.6W Titanium:sapphire lasers with a phase noise of -138dBc/Hz at 1MHz from the carrier, using an intra-cavity electro-optic phase modulator.

Noise Properties of Superconducting Coplanar Waveguide Microwave Resonators [PDF]

open access: yes, 2007
We have measured noise in thin-film superconducting coplanar waveguide resonators. This noise appears entirely as phase noise, equivalent to a jitter of the resonance frequency.

Characterization of Power-to-Phase Conversion in High-Speed P-I-N Photodiodes

open access: yes, 2011
Fluctuations of the optical power incident on a photodiode can be converted into phase fluctuations of the resulting electronic signal due to nonlinear saturation in the semiconductor.

Phase Separation Driven by External Fluctuations [PDF]

open access: yes, 1997
The influence of external fluctuations in phase separation processes is analysed. These fluctuations arise from random variations of an external control parameter.

On Phase Noise Suppression in Full-Duplex Systems [PDF]

open access: yes, 2014
Oscillator phase noise has been shown to be one of the main performance limiting factors in full-duplex systems. In this paper, we consider the problem of self-interference cancellation with phase noise suppression in full-duplex systems. The feasibility

Phase noise due to vibrations in Mach-Zehnder atom interferometers

open access: yes, 2006
Atom interferometers are very sensitive to accelerations and rotations. This property, which has some very interesting applications, induces a deleterious phase noise due to the seismic noise of the laboratory and this phase noise is sufficiently large ...

Oscillator Phase Noise and Small-Scale Channel Fading in Higher Frequency Bands [PDF]

open access: yes, 2014
This paper investigates the effect of oscillator phase noise and channel variations due to fading on the performance of communication systems at frequency bands higher than 10GHz.

Optimal entrainment of circadian clocks in the presence of noise

open access: yes, 2017
Circadian clocks are biochemical oscillators that allow organisms to estimate the time of the day. These oscillators are inherently noisy due to the discrete nature of the reactants and the stochastic character of their interactions.

A 12MHz Switched-Capacitor Relaxation Oscillator with a Nearly Minimal FoM of -161dBc/Hz [PDF]

open access: yes, 2008
In this work the phase noise performance of relaxation oscillators has been analyzed resulting in simple though precise phase noise expressions. These expressions have lead to a new relaxation oscillator topology, which exploits a noise filtering ...

Self-Interference Cancellation Using Time-Domain Phase Noise Estimation in OFDM Full-Duplex Systems

open access: yes, 2016
In full-duplex systems, oscillator phase noise (PN) problem is considered the bottleneck challenge that may face the self-interference cancellation (SIC) stage especially when orthogonal frequency division multiplexing (OFDM) transmission scheme is ...
