Analytical expression for mode-coherence coefficient of a uniformly-distributed wave propagating in different homogeneous media


Abstract: Presented is a derivation of an analytical expression for the mode-coherence coefficients of uniform-distributed wave propagating within different homogeneous media-as in the case of hyperbolic Gaussian beams-and a simple method involving the superposition of two such beams is proposed. The results obtained from this work are very applicable to study and analysis of Hermite-Gaussian beam propagation, especially in the problems of radiation-matter interaction, and laser beam propagation such as employed in free-space and fiber optical communications.

Keywords: Wave propagation, mode coherence coefficient, Gaussian beams, uniformly-distributed waves
