Abstract
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.
