Orbital angular momentum control of third-harmonic generation and vortex dichroism in isotropic media
Szymon Kurkowski, Kayn A Forbes
Structured light carrying orbital angular momentum enables new regimes of nonlinear light-matter interaction. Here we develop a molecular quantum electrodynamics description of thi…
Topological Control of Chirality and Spin with Structured Light
Light Mkhumbuza, Pedro Ornelas, Angela Dudley +2
Structured light beams with engineered topological properties offer a powerful means to control spin angular momentum (SAM) and optical chirality, key quantities shaped by spin-orb…
Vortex Light at the Nanoscale: Twists, Spins, and Surprises -- A Review
Kayn A Forbes
For over three decades, the study of optical vortex beams carrying orbital angular momentum (OAM) has been at the forefront of optics, driven by fundamental questions about optical…
Generalized Polarization Matrix Approach to Near-Field Optical Chirality
Kayn A. Forbes, David L. Andrews
For paraxial light beams and electromagnetic fields, the Stokes vector and polarization matrix provide equivalent scalar measures of optical chirality, widely used in linear optics…
Generating optical angular momentum through wavefront curvature
Kayn A. Forbes, Vittorio Aita, Anatoly V. Zayats
Recent developments in the understanding of optical angular momentum have resulted in many demonstrations of unusual optical phenomena, such as optical beams with orbital angular m…
Laguerre-Gaussian modes become elegant after an azimuthal phase modulation
Vasilios Cocotos, Light Mkhumbuza, Kayn A. Forbes +3
Laguerre-Gaussian (LG) modes are solutions of the paraxial Helmholtz equation in cylindrical coordinates and are associated with light fields carrying orbital angular momentum (OAM…
