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 …

Compressible Hydrodynamics of Few Body Optical Vortices
<p>The ubiquity of vortices nearly rivals that of the innumerable fluids and spaces in which they live. Not only do they exist in systems such as superfluids, superconductors, optical fields, or cold atomic gases, for example, but they also exist in our atmospheres, oceans, and even in our veins. …

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 …

Orbital angular momentum and fully structured light in nonlinear media and cavities
… mechanism for producing two dimensional optical rogue waves in a turbulent state driven by vortices with helical wavefronts. Self-organising hexagonal structures bound in phase lose stability and synchronised oscillations are unstable leading to phaseunbound vortex-mediated turbulence …

Bridging the Geometric and Quantum Information of Structured Light
<p>In this Dissertation, we review the several advances we have developed for preparing and measuring the geometric and quantum information of structured light. The geometric phase acts as a memory of transformations undertaken by physical processes; quantum entanglement underpins quantum …

Surface-emitting lasers for communications: novel metal-cavity microlasers and high-contrast-grating tunable VCSELs
… micro and nanolasers using metal cavities for optical confinement is discussed. Theoretical modeling of quantum-well and quantum-dot emission properties, as well as experimental characterization of their coupling with optical cavities, are presented. Lasing behavior of our designed and …
