<title>New description of interference in fiber optics including coherence and polarization</title>

Abstract

The interference of light in single-mode optical fiber is presented in the report. Both the coherence and the polarization of interfered light beams are taken into account in the proposed description due to applying the Jones matrix calculus. The resulting formula for source of Gaussian or Lorentzian spectral distribution makes possible estimating the influence of each parameter on the interference of light in the optical fiber. It can be used also to explaining the Fresnel's and Arego's conditions for the interference of polarized light beams.
