Abstract
The mutual intensity of the optical field in the Fraunhofer diffraction region from the end of an optical fiber is analyzed theoretically by using a fiber-end source model. Tn this source model, the optical field at the end of the fiber is expressed as a sum of independent plane waves with random directions and phases since the guided modes propagating through an optical fiber may be regarded as a stochastic process. It is found that the spatial coherence property of the optical field in the diffraction region is not homogeneous but quasihomogeneous in a statistical sense. This property is discussed in connection with the V number of the fiber and in comparison with that of the optical field, obeying the van Cittert-Zernike theorem, produced by the incoherent source.
