Author:Mabena, Chemist M; Bell, Lebohang T; Roux, FSDate:Feb 2019The 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 ...Read more
Author:Ngcobo, Sandile; Litvin, I; Burger, L; Forbes, ADate:Aug 2013Customizing the output beam shape from a laser invariably involves specialized optical elements in the form of apertures, diffractive optics and free-form mirrors. Such optics require considerable design and fabrication effort and suffer from ...Read more
Author:Bell, Teboho; Ngcobo, Sandile; Haddadi, S; Ait-Ameur, K; Forbes, ADate:Jul 2015Using the digital laser one can generate various types of modes, like, Laguerre-Gaussian modes. The digital laser was forced to generate high-order radial Laguerre-Gaussian modes, LGp , with zero azimuthal order, by loading a digital hologram ...Read more
