Corroboration of a multi-phase screen model

Author: Mabena, Chemist M ; Bell, Lebohang T ; Roux, FS Date: Feb 2019 The solution of the infinitesimal propagation equation for atmospheric propagation of single-photon and entangled quantum states, represented in terms of Laguerre-Gauss modes, which is a discrete orbital angular momentum (OAM) basis, is ...

Design and FDTD simulation of photonic crystal based sensor for biosensing applications

Author: Manoto, Sello L ; Mabena, Chemist M ; Malabi, Rudzani ; Ombinda-Lemboumba, Saturnin ; Mthunzi-Kufa, Patience Date: Mar 2019 Photonic crystals (PhCs) is a unique and flexible class of optical devices that are able to manipulate the electromagnetic fields of light. PhCs is a subwavelength grating structure with a periodic arrangement of a high refractive index layer ... Read more
High-dimensional quantum channel estimation using classical light

Author: Mabena, Chemist M ; Roux, FS Date: Nov 2017 A method is proposed to characterize a high-dimensional quantum channel with the aid of classical light. It uses a single nonseparable input optical field that contains correlations between spatial modes and wavelength to determine the effect ... Read more
Optical orbital angular momentum under strong scintillation

Author: Mabena, Chemist M ; Roux, FS Date: Jan 2019 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 infinitesimal propagation equation (IPE), a multiphase screen ... Read more
Smartphone biosensing for point of care diagnostics

Author: Manoto, Sello L ; Mabena, Chemist M ; Malabi, Khorommbi P ; Ombinda-Lemboumba, Saturnin ; El-Hussein, A ; Kasem, M ; Lugongolo, Masixole Y ; Mthunzi-Kufa, Patience Date: Feb 2020 A lot of individuals residing in resource limited settings where timely access to medical care is a challenge and healthcare infrastructure is usually poor have no access to laboratory facilities. Disease diagnosis in such sites is dependent ... Read more
Turbulence and the Hong-Ou-Mandel effect

Author: Prabhakar, Shashi ; Mabena, Chemist M ; Konrad, T ; Roux, FS Date: Jan 2018 The effect of a decoherence channel, such as a turbulent atmosphere, on the second-order quantum interference in the Hong-Ou-Mandel (HOM) effect is investigated. The investigation includes both theoretical analyses and an experimental ... Read more
