Probing the limits of vortex mode generation and detection with spatial light modulators
Jonathan Pinnell, Valeria Rodriguez-Fajardo, Andrew Forbes
Spatial light modulators (SLMs) are popular tools for generating structured light fields and have fostered numerous applications in optics and photonics. Here, we explore the limit…
Spatial filtering of structured light
Jonathan Pinnell, Asher Klug, Andrew Forbes
Spatial filtering is a commonly deployed technique to improve the quality of laser beams by optically filtering the noise. In the "textbook" example, the noise is usually assumed t…
Revealing the modal content of obstructed beams
Jonathan Pinnell, Saoussene Chabou, Karima Mihoubi +3
In this work, we propose a predictor/indicator of the self-healing ability of coherent structured light beams: the field's modal content. Specifically, the fidelity between the obs…
Experimental quantum secret sharing with spin-orbit structured photons
Michael de Oliveira, Isaac Nape, Jonathan Pinnell +2
Secret sharing allows three or more parties to share secret information which can only be decrypted through collaboration. It complements quantum key distribution as a valuable res…
Experimental 11-dimensional secret sharing with Perfect Vortex beams
Jonathan Pinnell, Isaac Nape, Michael De Oliveira +2
Secret sharing is the art of securely sharing information between more than two people in such a way that its reconstruction requires the collaboration of a certain number of parti…
How Perfect are Perfect Vortex Beams?
Jonathan Pinnell, Valeria Rodriguez-Fajardo, Andrew Forbes
Perfect (optical) vortex (PV) beams are fields which are mooted to be independent of the orbital angular momentum (OAM) they carry. To date, the best experimental approximation of…
Single-Step Shaping of the Orbital Angular Momentum Spectrum of Light
Jonathan Pinnell, Valeria Rodriguez-Fajardo, Andrew Forbes
Control of orbital angular momentum (OAM) in optical fields has seen tremendous growth of late, with a myriad of tools existing for their creation and detection. What has been lack…
Quantitative orbital angular momentum measurement of perfect vortex beams
Jonathan Pinnell, Valeria Rodriguez-Fajardo, Andrew Forbes
Perfect (optical) vortices (PVs) have the mooted ability to encode orbital angular momentum (OAM) onto the field within a well-defined annular ring. Although this makes the near-fi…
