摘要
We built the cross-spectral density matrix elements analytical expression of random electromagnetic Gaussian vortex (REGV) beam propagating in gradient-index (GRIN) fiber, which is used to study the polarization properties of the beam. The distribution of spectral degree of polarization (SDOP) and state of polarization (SOP) show the same periodicity and symmetry. The distribution law of SDOP and SOP is unchanging with the topological charge m changing and is changed by adjusting the spatial self-correlation length sigma(xx). The research results have guiding significance for the propagation of random electromagnetic vortex beams in optical fibers, which could be considerable value in high-speed and large-capacity optical fiber secure communication.
