Optical orbital angular momentum under strong scintillation
Chemist M. Mabena, Filippus S. Roux
The evolution of classical optical fields propagating through atmospheric turbulence is investigated under arbitrary conditions. We use the single-phase screen (SPS) method and the…
Robust entangled qutrit states in atmospheric turbulence
Tobias Bruenner, Filippus S Roux
The entangled quantum state of a photon pair propagating through atmospheric turbulence suffers decay of entanglement due to the scintillation it experiences. Here we investigate t…
Observing the decay of orbital angular momentum entanglement, through experimentally simulated turbulence
Alpha Hamadou Ibrahim, Filippus S. Roux, Sandeep Goyal +3
We study the evolution of an orbital angular momentum (OAM) entangled bipartite photonic state for the case where one of the photons propagates through Kolmogorov turbulence, using…
Orbital angular momentum spectrum of Bessel-Gaussian modes, as generated by spontaneous parametric down-conversion
Filippus S. Roux
The Bessel-Gaussian modal spectrum, generated in spontaneous parametric down-conversion of a Gaussian pump beam, is considered. This is done by first deriving a general expression…
Infinitesimal propagation equation for atmospheric decoherence with multiphoton correlations
Filippus S. Roux
Previously a set of coupled first order differential equations were derived for the decoherence of a pair of spatial mode entangled photons, propagating along different paths throu…
Infinitesimal propagation equation for decoherence of an OAM entangled biphoton in atmospheric turbulence
Filippus S. Roux
We derive a first order differential equation for the decoherence of an orbital angular momentum entangled biphoton state propagating through a turbulent atmosphere. The derivation…
