Knotting of optical vortices
Optical vortices form three-dimensional lines of darkness in scalar light. They are places where the phase becomes undefined and hence singular in value. We study the ability of optical vortices to form knots and links of darkness in scalar optical fields. We describe a construction to create …

A QED framework for nonlinear and singular optics
… in the description of linear and nonlinear optical effects. We study the effects of using a two energy level approximation in simplifying expressions obtained from perturbation theory, equivalent to truncating the completeness relation. However, applying a two-level model with a lack of …

Probing Random Media With Singular Waves
… of interest in wave singularities (of which optical vortices are a prominent example), light angular momentum and the relations between them has occurred. Many applications in various areas of linear and non-linear optics have been based on studying effects related to angular momentum and …
