The singularities of light: intensity, phase, polarisation

Light: Science & Applications, 2023
In modern optics, light can be described at different levels: as rays, as scalar waves, as vector fields, and as quantum fields. In the first three levels, there are singularities—characteristic features, useful in interpreting phenomena at that level ...
