Singular optics empowered by engineered optical materials [PDF]
Nanophotonics, 2023 Abstract The rapid development of optical technologies, such as optical manipulation, data processing, sensing, microscopy, and communications, necessitates new degrees of freedom to sculpt optical beams in space and time beyond conventionally used spatially homogenous amplitude, phase, and polarization. Structuring light in space and

Ukraine and singular optics. [PDF]
Nanophotonics, 2023 Abstract The mostly theoretical viewpoint, in which light is understood in terms of its singularities – caustics, phase vortices and lines of circular and linear polarisation – was developed in Bristol in the 1970s and 1980s. Starting in the 1990s, research by physicists in Ukraine, principally by Marat Soskin, stimulated the ...

Hybridization of singular plasmons via transformation optics [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Surface plasmons, which are optical resonances supported by metallic nanostructures, are extremely useful for manipulating light on the nanoscale. However, designing novel plasmonic devices becomes quite challenging when the desired spectral response pattern is highly complex.

The plurality of optical singularities [PDF]
Journal of Optics A: Pure and Applied Optics, 2004 This collection of papers arose from an Advanced Research Workshop on Singular Optics, held at the Bogolyubov Institute in Kiev, Ukraine, during 24–28 June 2003. The workshop was generously financed by NATO, with welcome additional support from Institute of Physics Publishing and the National Academy of Sciences of Ukraine.

Partial transmutation of singularities in optical instruments [PDF]
Journal of Optics, 2011 Some interesting optical instruments such as the Eaton lens and the Invisible Sphere require singularities of the refractive index for their implementation. We show how to transmute those singularities into harmless topological defects in anisotropic media without the need for anomalous material properties.

Polarization singularities in a stress-engineered optic
Journal of the Optical Society of America A, 2019 We develop a simplified version of a recently presented model to simulate the oblique propagation of polarized light through a thick birefringent element known as a stress-engineered optic (SEO). We use this model to analyze the formation and evolution of three polarization singularities, stars, lemons, and monstars, and experimentally verify the ...
