    The orbital angular momentum (OAM) of light has become the focus of intensive research. Traditional optical communication systems optimize multiplexing in the polarization and the wavelength of light to attain an increase ...
  • Duvenhage, B; Bouatouch, K; Kourie, DG (ACM Digital Library, 2014-09)
    This paper describes a new extension to light beam tracing that includes glossy multi-bounce transport paths for more realistic rendering of caustics. A spherical Gaussian approximation of the glossy scatter distribution ...
  • Lavery, MPJ; Dudley, Angela L; Forbes, A; Courtial, J; Padgett, MJ (Institute of Physics, 2011-09)
    The authors have developed an interferometer requiring only minimal angular alignment for the routing of beams carrying orbital angular momentum. The Mach–Zehnder interferometer contains a Dove prism in each arm where each ...
  • Forbes, A; Dudley, Angela L; Roux, S (EE Publishers, 2010-12)
    Research at the Mathematical Optics Group uses "twisted" light to study new quatum-based information security systems. In order to understand the structure of "twisted" light, it is useful to start with an ordinary light ...
