Abstract

We construct the coherent-mode representation for fluctuating, statistically stationary electromagnetic fields. The modes are shown to be spatially fully coherent in the sense of a recently introduced spectral degree of electromagnetic coherence. We also prove that the electric cross-spectral density tensor can be rigorously expressed as a correlation tensor averaged over an appropriate ensemble of strictly monochromatic vectorial wave functions. The formalism is demonstrated for partially polarized, partially coherent Gaussian Schell-model beams, but the theory applies to arbitrary random electromagnetic fields and can find applications in radiation and propagation and in inverse problems.

  22. A number of recent papers consider beams in which the field consists of orthogonal, partially correlated transverse modes. The cross-spectral density then has, besides the “diagonal” elements, nonzero “off-diagonal” elements, and hence the represention is not the coherent-mode decomposition.

An alternative definition for the degree of electromagnetic coherence in the space–time domain, based on the visibility of interference fringes in Young’s double-slit experiment, was introduced in 1963 by Karczewski.49 50 Several consequences of such a definition have been discussed.29 A space–frequency analog of this degree of electromagnetic coherence was later employed in radiation analysis, 51 52 and in 2003 it was formalized by Wolf for electromagnetic beams in the two-slit interference geometry.53
