Subtracting the photon noise bias from single-mode optical interferometer visibilities

چکیده
I present in this paper a method to subtract the bias due to source photon noise from visibilities measured with a single-mode optical interferometer. Properties of the processed noise are demonstrated and examples of subtraction on real data are presented.

متن کاملSingle-photon Sagnac interferometer
We present the first experimental demonstration of the optical Sagnac effect at the single-photon level. Using a high quality guided-wave heralded singlephoton source at 1550 nm and a fibre optics setup, we obtain an interference pattern with net visibilities up to (99.2 ± 0.4%). On the basis of this high visibility and the compactness of the setup, the interest of such a system for fibre optic...
متن کاملFringe visibility estimators for the Palomar Testbed Interferometer
Visibility estimators and their performance are presented for use with the Palomar Testbed Interferometer (PTI). One operational mode of PTI is single-baseline visibility measurement using pathlength modulation with synchronous readout by a NICMOS-3 infrared array. Visibility is estimated from the fringe quadratures, either incoherently, or using source phase referencing to provide a longer coh...

The drawing of frequency-path (F-P) models of optical beams is an approach for nonlinearity analysis in nano-metrology systems and sensors based on the laser interferometers. In this paper, the frequency-path models of four nano-metrology laser interferometry systems are designed, analyzed and simulated, including ...
متن کاملCooper-Pair Molasses - Cooling a Nanomechanical Resonator with Quantum Back-Action
Quantum mechanics demands that measurement must affect the measured object. When continuously monitoring position with a linear amplifier the Heisenberg uncertainty relationship requires that the object be driven by force impulses, called back-action 1,2,3. Here we report the detection of the measurement back-action of a superconducting single-electron transistor (SSET) which measures the posit...
