Vector mode decay in atmospheric turbulence: a quantum inspired analysis
Isaac Nape, Nikiwe Mashaba, Nokwazi Mphuthi +3
Vector beams are inhomogeneously polarized optical fields with nonseparable, quantum-like correlations between their polarisation and spatial components, and hold tremendous promis…
Experimental generation of Helical Mathieu-Gauss vector modes
Carmelo Rosales-Guzmán, Xiao-Bo Hu, ValeriaRodríguez-Fajardo +3
Vector modes represent the most general state of light in which, the spatial and polarisation degrees of freedom are coupled in a non-separable way. Crucially, while polarisation i…
Free-space non-separability decay of clasicaly-entangled modes
Xiao-Bo Hu, Benjamin Perez-Garcia, Valeria Rodríguez-Fajardo +3
One of the most prominent features of quantum entanglement is its invariability under local unitary transformations, which implies the degree of entanglement remains constant durin…
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…
Structured Light in Turbulence
Mitchell A. Cox, Nokwazi Mphuthi, Isaac Nape +3
Optical communication is an integral part of the modern economy, having all but replaced electronic communication systems. Future growth in bandwidth appears to be on the horizon u…
Improving the beam quality factor () by phase-only reshaping of structured light
Stirling Scholes, Andrew Forbes
Laser brightness is crucial in many optical processes, and is optimised by high power, high beam quality (low ) beams. Here we show how to improve the laser beam quality facto…
