Abstract

By using the extended Huygens-Fresnel principle and the definition of Wigner distribution function, influence of turbulent biological tissues on the propagation quality of VPCHG beam is studied by the derived analytical expressions. The numerical simulation results show that the effective radius of curvature of a VPCHG beam is smaller with decreasing beam width, decreasing the coherence width or decreasing beam order in turbulent biological tissues, and effect of the beam wavelength on the ERC of a VPCHG beam is slight. Besides, the normalized M²-factor of a VPCHG beam with smaller beam width or coherence width spreads slower than that of those with lager numbers, which implies that a VPCHG beam is less affected by the turbulent biological tissues. Additionally, the normalized M²-factor of a VPCHG beam is more smaller with the larger beam orders or larger beam wavelength. The propagation quality of a VPCHG beam would be controlled in turbulent biological tissues optical communications
