Dynamic Mueller matrix polarimetry using generalized measurements
Amy McWilliam, Mustafa A. Al Khafaji, Sphinx J. Svensson +2
Mueller matrices provide a complete description of a medium's response to excitation by polarized light, and their characterization is important across a broad range of application…
Theory of paraxial optical Skyrmions
Z. Ye, S. M. Barnett, S. Franke-Arnold +4
Vector light beams, characterised by a spatially varying polarisation, can exhibit localised structures reminiscent of the Skyrmions familiar from the study of magnetic media. We p…
Real-time buffer gas pressure tuning in a micro-machined vapor cell
S. Dyer, A. McWilliam, D. Hunter +7
We demonstrate a controllable depletion of the nitrogen buffer gas pressure in a micro-machined cesium (Cs) vapor cell from the dynamic heating of an alkali dispenser pill. When th…
Topological approach of characterizing optical Skyrmions and Skyrmion lattices
A. McWilliam, C. M. Cisowski, Z. Ye +4
The Skyrmion number of paraxial optical Skyrmions can be defined solely via their polarization singularities and associated winding numbers, using a mathematical derivation that ex…
Angular momentum redirection phase of vector beams in a non-planar geometry
Amy McWilliam, Claire Marie Cisowski, Robert Bennett +1
An electric field propagating along a non-planar path can acquire geometric phases. Previously, geometric phases have been linked to spin redirection and independently to spatial m…
Revealing the invariance of vectorial structured light in perturbing media
Isaac Nape, Keshaan Singh, Asher Klug +5
Optical aberrations have been studied for centuries, placing fundamental limits on the achievable resolution in focusing and imaging. In the context of structured light, the spatia…
