Radial modes in phase-only twisted light beams

Author: Sephton, Bereneice C ; Dudley, Angela L Date: Aug 2017 Beams carrying orbital angular momentum (OAM) are ubiquitous in many experiments carried out today and cover a wide range of research, from surface microstructure processing to optical tweezers and communications. It follows that these beams ... Read more
Revealing the radial modes in vortex beams

Author: Sephton, Bereneice C ; Dudley, Angela L ; Forbes, A Date: Oct 2016 Light beams that carry orbital angular momentum are often approximated by modulating an initial beam, usually Gaussian, with an azimuthal phase variation to create a vortex beam. Such vortex beams are well defined azimuthally, but the radial ... Read more
Towards non-classical walks with bright laser pulses

Author: Sephton, Bereneice C ; Dudley, Angela L ; Forbes, A Date: Aug 2017 In the avid search for means to increase computational power in comparison to that which is currently available, quantum walks (QWs) have become a promising option with derived quantum algorithms providing an associated speed up compared to ...

Vortex beam characterization in terms of Hypergeometric- Gaussian modes

Author: Sephton, Bereneice C ; Dudley, Angela L ; Forbes, A Date: Oct 2016 Q-plates are commonly used for uncomplicated generation of polarization controlled vortex beams. Here we show experimentally that the output is not a pure vortex but rather a Hypergeometric-Gaussian mode. Results are in good agreement with theory. Read more
