Superoscillations: a scale physics perspective
Thomas Konrad, Filippus S. Roux
Arguments from scale physics, augmented by numerical and analytical investigations, are used to consider the probability and the detectability of superoscillations in generic funct…
Spatial mode detection by frequency upconversion
Bereneice Sephton, Adam Vallés, Fabian Steinlechner +4
The efficient creation and detection of spatial modes of light has become topical of late, driven by the need to increase photon-bit-rates in classical and quantum communications.…
Controlled generation of higher-order Poincare sphere beams from a laser
Darryl Naidoo, Filippus Roux, Angela Dudley +4
The angular momentum state of light can be described by positions on a higher-order Poincaré (HOP) sphere, where superpositions of spin and orbital angular momentum states give ris…
Detection of Bessel beams with digital axicons
Abderrahmen Trichili, Thandeka Mhlanga, Yaseera Ismail +4
We propose a simple method for the detection of Bessel beams with arbitrary radial and azimuthal indices, and then demonstrate it in an all-digital setup with a spatial light modul…
Angular acceleration with twisted light
Christian Schulze, Filippus S. Roux, Angela Dudley +3
There is significant interest in tailoring wave packets that transversely accelerate during propagation. The first realisation was in the optical domain, the Airy beam. Valid in th…
Entangled Bessel beams
Melanie McLaren, Megan Agnew, Jonathan Leach +3
Orbital angular momentum (OAM) entanglement is investigated in the Bessel-Gauss (BG) basis. Having a readily adjustable radial scale, BG modes provide a more favourable basis for O…
