It is shown that the intensity correlation function is central to the understanding of various aspects of nonclassicality of the electromagnetic field, e.g. quantum interference, antibunching, nonclassical statistics, squeezing and nonlocality. Particular emphasis is given on correlations of twin signals generated in nonlinear mixing interactions. © 1994 Indian Academy of Sciences.
