Singular optics and topological photonics [PDF]

Journal of Optics, 2016
For centuries, singularities in wave fields have been a mainstay of interest in multiple areas of physics, ranging from plasma physics, fluid dynamics and atmospheric physics to optics and photonics [1].

Singular Electromagnetics: From Phase Singularities to Optical Skyrmions and Beyond

Advanced Physics Research
Singular electromagnetics, also known as singular optics in the visible spectrum, is a branch of modern electromagnetics/optics that studies the solutions with nontrivial topological features to Maxwell's equations under different boundary conditions ...

Rotationally induced vortices in optical cavity modes [PDF]

, 2009
We show that vortices appear in the modes of an astigmatic optical cavity when it is put into rotation about its optical axis. We study the properties of these vortices and discuss numerical results for a specific realization of such a set-up. Our method

Stable multiple-charged localized optical vortices in cubic-quintic nonlinear media [PDF]

, 2003
The stability of two-dimensional bright vortex solitons in a media with focusing cubic and defocusing quintic nonlinearities is investigated analytically and numerically. It is proved that above some critical beam powers not only one- and two-charged but

Propagation of Correlation Singularities of a Partially Coherent Laguerre–Gaussian Electromagnetic Beam in a Uniaxial Crystal

IEEE Photonics Journal, 2017
The correlation singularities of a partially coherent Laguerre–Gaussian (LG) electromagnetic beam in a uniaxial crystal is shown to possess interesting evolution behavior. The analytical formula for the cross-spectral density matrix of a partially

Boosted Kerr Black Hole in the Presence of Plasma

Proceedings, 2019
In this work, we obtain the deflection angle for a boosted Kerr black hole in the weak field approximation using the optics in a curved spacetime developed by J. L. Synge in 1960.
