Extraneous motion of optical elements in an interferometer leads to excess noise. Typically, fluctuations in the effective path length lead to phase noise, while beam pointing fluctuations lead to apparent amplitude noise. For a transmissive optic moving along the optical axis, neither effect should exist. However, relativity of motion suggests that, even in this case, small corrections of order v/c (v the velocity of the optic) give rise to phase and amplitude noise on the light. Here we…

An analytic study of light propagation in a simple Michelson-Morley interferometer as observed by inertial observers finds that relativistic and other effects appear naturally as a result of finite light speed.


Noise in interferometric optical systems: an optical Nyquist theorem
The index of refraction of an optical medium at a temperature above absolute zero undergoes statistical fluctuations, which in turn introduce fluctuations in the phase of an optical signal
Quantum Mechanical Noise in an Interferometer
The interferometers now being developed to detect gravitational waves work by measuring the relative positions of widely separated masses. Two fundamental sources of quantum-mechanical noise
Fundamental phase noise limit in optical fibres due to temperature fluctuations
Theoretical results are presented for the power and RMS amplitude spectra of phase noise in optical fibres due to thermodynamic temperature fluctuations, including the effects of finite fibre outside
General-relativistic treatment of the gravitational coupling between laser beams
The present paper is an extension of the earlier work of Tolman, Ehrenfest, and Podolsky who investigated the gravitational interaction between ''thin pencils of light.'' We calculate the
General treatment of the thermal noises in optical fibers
A general framework based on the fluctuation-dissipation theorem has been outlined for the study of the spontaneous thermal fluctuations in optical fibers. The goal is to seek a unified scheme to

I construct models for the thermal noise spectra of systems with more than one mode of vibration, and evaluate a model of a specific design of pendulum suspension for the test masses in a gravitational-wave interferometer.
Observation of Radiation Pressure Shot Noise on a Macroscopic Object
This work monitors a mechanical resonator subject to an increasingly strong continuous position measurement and observes a quantum mechanical back-action force that rises in accordance with the Heisenberg uncertainty limit and demonstrates a back- action force that is comparable in magnitude to the thermal forces in the system.
Influence of motion of the medium on the velocity of light
THE only work of any consequence, on the influence upon the velocity of light of the motion of the medium through which it passes, is the experiment of Fizeau. He announced the remarkable result that
