Spectrum of Atmospheric Turbulence [PDF]
Nature, 1951 DR. E. C. S. MEGAW1 opens his valuable contribution to this subject with a challenging remark. He says, “knowledge of the average properties of turbulence in the free atmosphere is almost totally lacking”. Actually, so many meteorologists have published observations that it would be impossible here to give an adequate list of them. As long ago as 1926,

Optics Letters, 2016 We explore the mitigation of atmospheric turbulence effects for orbital angular momentum (OAM)-based free-space optical (FSO) communications with multiple-input multiple-output (MIMO) architecture.

Measuring anisotropy ellipse of atmospheric turbulence by intensity correlations of laser light.
Optics Letters, 2017 An experimental study has been performed of a laser beam propagating horizontally through the near-ground atmosphere above a grassy field at the University of Miami (UM) Coral Gables campus.

Gaussian entanglement in the turbulent atmosphere [PDF]
Physical Review A, 2016 We provide a rigorous treatment of the entanglement properties of two-mode Gaussian states in atmospheric channels by deriving and analyzing the input-output relations for the corresponding entanglement test. A key feature of such turbulent channels is a non-trivial dependence of the transmitted continuous-variable entanglement on coherent ...

Bell nonlocality in the turbulent atmosphere [PDF]
Physical Review A, 2016 Violations of Bell inequalities are better preserved by turbulent atmospheric channels than by comparable optical fibers in the scenario of copropagating entangled photons [A.A. Semenov and W. Vogel, Phys. Rev. A 81, 023835 (2010); arXiv:0909.2492]. Here we reexamine this result for the case of counterpropagation also considering the fact that each ...

Optics Express, 2016 The radial average-power distribution and normalized average power of orbital-angular-momentum (OAM) modes in a vortex Gaussian beam after passing through weak-to-strong atmospheric turbulence are theoretically formulated. Based on numerical calculations,

Atmospheric Quantum Channels with Weak and Strong Turbulence. [PDF]
Physical Review Letters, 2016 The free-space transfer of high-fidelity optical signals between remote locations has many applications, including both classical and quantum communication, precision navigation, clock synchronization, etc.

Free-space to few-mode-fiber coupling under atmospheric turbulence.
Optics Express, 2016 High speed free space optical communication (FSOC) has taken advantages of components developed for fiber-optic communication systems. Recently, with the rapid development of few-mode-fiber based fiber communication systems, few-mode-fiber components ...

Influence of non-Kolmogorov atmospheric turbulence on the beam quality of vortex beams.
Optics Express, 2016 Based on the extended Huygens-Fresnel principle and the definition of second-order moments of the Wigner distribution function (WDF), the analytical expressions for the propagation factors (M2-factors) and Strehl ratio SR of the Gaussian Schell-model ...
