Abstract

In this paper we examine particle density fluctuations as an intrinsic source of noise in an artificial Kerr medium. A general method is developed for determining spontaneous grating fluctuations (identified here as a form of thermal noise) directly from the equilibrium grating response to an applied electromagnetic field. Calculations are given for the predicted root-mean-square (RMS) signal fluctuations in four-wave mixing and compared with experiment. Grating fluctuations are shown to account for the previous discrepancy between predicted and measured RMS fluctuations in the conjugate wave signal generated from an aqueous polystyrene microsphere suspension.
