The effect of heterodyne detection on the statistical accuracy of optical linewidth measurements

Abstract

It is shown that an order of magnitude gain in the statistical accuracy of optical linewidths measured by digital autocorrelation of photon- counting fluctuations may be achieved by heterodyne detection in the weak signal limit.

Statistical accuracy in the digital autocorrelation of photon counting fluctuations

Eric Jakeman, Edward R. Pike, S. Swain

Optical measurements by intensity fluctuation spectroscopy are subject to errors arising from the statistical nature of light and of the photo-detection process. The authors report the results of a calculation of the expected errors, due to these causes, in linewidth measurements by digital autocorrelation of photon counting fluctuations.

Statistical accuracy in the digital autocorrelation of photon counting fluctuations

Eric Jakeman, Edward R. Pike, S. Swain

The authors investigate the statistical errors which arise in digital autocorrelation of photon counting fluctuations due to the finite duration of experiments. An expression for the accuracy with which individual points of the autocorrelation function of intensities can be measured is derived analytically and evaluated for Gaussian- Lorentzian light. The appropriate weighting for a 'least-squares' fitting procedure is determined and the error in spectral linewidth, obtained by this procedure from experiment, is calculated.

THE ACCURACY OF DIFFUSION-CONSTANT MEASUREMENTS BY DIGITAL AUTOCORRELATION OF PHOTON-COUNTING FLUCTUATIONS

Edward R. Pike

We discuss the accuracy of a measurement of a spectral linewidth using the method of digital correlation of single-clipped photon counting fluctuations with a given light flux and a given duration of experiment. Statistical effects due to the random nature of the light field and the photoelectric process limit this accuracy, so that the longer the duration of the experiment the more accurate the result, if all other factors are equal. Theoretical and experimental results are presented which show the accuracies obtainable as functions of the sample time, detector area and clipping level.

Theory of optical spectroscopy by digital autocorrelation of photon-counting fluctuations

Eric Jakeman

Digital autocorrelation of optical signals is discussed with particular reference to the technique of clipping, reported briefly in an earlier publication. A detailed analysis of the relationship between the autocorrelation functions of clipped and unclipped photon-counting fluctuations is given. By evaluating the generating function for the joint distribution of intensity fluctuations, corrections to the earlier results are calculated which arise if the time over which the signal is sampled is not negligible compared with any coherence time of the light. The effect of clipping in heterodyne experiments is also analysed.

A measurement of optical linewidth by photon-counting statistics

Eric Jakeman, Christopher J. Oliver, Edward R. Pike

An optical linewidth of 20 Hz of laser light scattered by spherical particles undergoing Brownian motion has been measured experimentally by photon-counting statistics using the theory of the intensity-fluctuation distribution of Gaussian-Lorentzian light.

Balanced-heterodyne detection of optical squeezing

Sheng Feng

We study the balanced-heterodyne detection of optical squeezing, for which the corresponding spectral density of the photocurrent fluctuations produced at the output of the photo-detector is calculated as the Fourier transform of their autocorrelation function. We show that, for maximal signal-to-noise ratio enhancement by use of squeezed states of light, an optical signal to be measured in this scheme must be carried in the squeezed quadrature of the carrier field. We discuss how this scheme may be exploited in gravitational-wave searching.
